Two projects, one lift session. Front rotors stay on the car — this changes the whole procedure.
Run these BEFORE buying anything, BEFORE lifting the car. Any NO-GO stops the job.
The retaining screws carry zero load — they only located the rotor on the assembly line. With the wheel torqued to 80 ft-lb, the rotor is clamped by the hub and cannot move. Leaving them alone keeps the existing rotor-to-hub seating intact, which is safer than disturbing a rusted interface that could trap debris and induce runout.
All four GATES green + screw head flush → proceed to Project 1 and Project 2.
Any gate red → stop. Thickness or judder failures mean new rotors, and the whole front procedure changes (see Reference tab).
Every tool this job touches, grouped by what you are doing with it. Green rows = you probably already own it. The shopping list at the bottom is what to actually go buy.
Where to Buy → Store-by-store guideNever work under a car held only by a jack. This corner is where the job can kill you.
| Item | Spec | Why / note |
|---|---|---|
| Floor jack | ≥2 ton | Stock ride height — an ordinary trolley jack clears it. Low-profile is not required. |
| Jack stands ×2 | 3 ton | Hard requirement. The car goes down on stands before any wheel comes off. 4 stands if you are doing front and rear in one session. |
| Wheel chocks ×2 | — | Chock the axle you are not lifting. |
| Secondary catch | — | Slide each removed wheel flat under the rocker panel. Free insurance. |
| Nitrile gloves | — | Brake dust + solvent. Change them when they get loaded. |
| Eye protection | — | Spinning surface-conditioning disc + brake cleaner spray. |
| Respirator / N95 | — | Brake dust contains metal particulate. Never dry-brush it into the air. |
| Item | Spec | Why / note |
|---|---|---|
| Breaker bar | 1/2″ drive, 18″+ | Cracks the lug nuts loose before you lift. |
| Torque wrench | covers 20–80 ft-lb | Read the range before buying. A 50–250 ft-lb wrench cannot measure the 25 ft-lb guide-pin spec. A 1/2″ 10–150 or a 3/8″ 5–80 is the useful window here. |
| Lug nut socket | 19 mm, 6-point, thin-wall | Honda factory lugs are 12×1.5 with a 19 mm hex. 6-point only — a 12-point rounds the corners. |
| Socket set | 6-point, 10–19 mm | You will actually use: 19 mm (lug nuts · rear bracket 55 ft-lb), 17 mm (front bracket — do not touch), and the guide-pin size (have 12 & 14 mm in the tray). |
| Extensions | 3″ + 6″ | Reach into the wheel arch without knuckle contact. |
| Hex keys | 5 mm | Rear EPB actuator housing, 2× cap screws. |
| E-Torx socket | E11 (have E12 too) | Rear EPB shaft retract. This is the one tool people get stuck on. Field fallback reported on CivicX: a 9 mm 6-point socket fits well enough. Buy the E11 if you can. |
| Piston compressor / C-clamp | — | Rear piston is a straight push. An old pad between the clamp and the new pad protects the face. |
| Vernier caliper | 0.1 mm resolution | Rotor thickness — the Go/No-Go gate. Front ≥21.0 mm, rear ≥8.0 mm. |
The 17 mm front caliper bracket bolts are not part of this job. The rotors stay on, so the bracket stays on. They are also the single most expensive fastener on the car to break: Honda sells no replacement bracket — only a whole caliper.
| Item | Spec | Why / note |
|---|---|---|
| Drill | variable speed, 3/8–1/2″ chuck | Must be variable speed. Single-speed is unusable — you need a slow spin, not a sander's pace. |
| 2″ surface-conditioning kit | RYOBI A911602 | Backer pad with a ¼″ shank + fine / medium / coarse discs. $27.22 at Home Depot. The ¼″ shank is what lets it go in a drill. |
| Hand pad (alternative) | 3M 7447, maroon / Very Fine | No power tools needed. Slower but cannot gouge — and it is what track-day regulars actually use when swapping compounds on a rotor that stays on the car. |
| Wire brush | — | Hub flange rust only. Never on the caliper bracket's pad-sliding surfaces — it scores them and the pad jams. |
Angle grinder: never on a rotor. Free-hand cutting at 10,000+ RPM produces thickness variation, which becomes pedal pulsation that cannot be undone.
Rotor hone (three-stone brush): documented by track forums as giving uneven results. Skip it.
Woodworking sandpaper: loads up instantly on metal and sheds grit. Wrong abrasive.
| Item | Spec | Why / note |
|---|---|---|
| Brake cleaner ×2 | NON-CHLORINATED | Chlorinated cleaner above 315°C decomposes into phosgene. Read the can — if it does not say Non-Chlorinated, assume it is not. |
| Lint-free cloths | 6+ | Spray and wipe, one direction. Change cloth as soon as it loads up. |
| Small detail brush | — | Caliper bracket pad rails. |
| Brake grease | high-temp silicone | Backing plate and pad ears only. A different product from anti-seize. |
| Copper anti-seize | Permatex 09128 | Rotor retaining screws — only relevant if they ever come out. Copper or nickel base; ordinary grease bakes into a hard crust on a rotor. |
| Item | Spec | Why / note |
|---|---|---|
| Autel AP200 | ~$69 | Preferred route — drives the EPB motors into service mode over OBD. Also reads every module on the car, resets oil life, and handles TPMS. Good long-term tool. |
| E11 E-Torx socket | ~$10 | Manual route — retract the screw by hand if you skip the scanner. |
| 5 mm hex key | — | Actuator housing, 2× cap screws. |
| C-clamp / piston tool | — | Straight push on the piston, after the screw is retracted. |
You can do the rear without any OBD tool. What you cannot do is skip the retract step, or push the piston before the screw is back. Both of those damage the ball screw permanently.
Assuming you already own the usual garage kit. Prices are as checked — verify at the store.
A911602$27.2220-BC 14 oz$5.80 eaPermatex 09128$8–12The front brakes are the ones doing the track-day work. Rotor surface prep is the step that decides whether the new pads ever bite properly.
Project 2 needs all four corners up. If this is one lift session, put it on four stands now (or plan a second lift for the rear) — but never mix: front on stands while the rear is on a jack.
Do not use a C-clamp to push the front piston in until you have checked the master-cylinder fluid level. Pushing a piston back sends fluid up the line. If the reservoir was topped up as the pads wore, it will overflow onto paint and wiring.
Check the level, have a rag around the reservoir cap, and open it before you retract the piston.
The first track day glazed the OEM rotors: a mirror-like transfer layer that the original pads baked on. A new pad compound bedded onto that film will not bond properly — it will slide, squeal, and glaze again. The goal is to strip the film back to bare, uniformly grey iron without changing the rotor's geometry.
Hand pads and Roloc discs use different colour grades. Maroon on a hand pad means Very Fine; maroon on a disc means Medium. Read the grade letters, not the colour: CRS = coarse, MED = medium, VFN = very fine.
Avoid the guide-pin boots, ABS wiring, wheel-speed sensors, and any painted rotor hat. The cleaner attacks rubber and paint. Also: do not use compressed air to blow brake dust around — it aerosolises metal particulate. Ventilation or outdoors.
Bedding transfers a thin, uniform layer of pad material onto the rotor face. That transfer layer is the friction surface — the pad-on-iron interface produces roughly 30% of the friction that pad-on-transfer-layer does. A partial or uneven layer produces vibration and green fade. This is why the rotor prep in Phase 3 matters: a clean, non-directional surface accepts the transfer layer evenly.
Bluestuff is factory pre-scorched, so 100 street miles of normal driving, with a handful of firm stops, is an accepted bed-in per EBC. Use the full two-cycle procedure above if you want the transfer layer maximally uniform before a track day. What is not optional: the rotor prep, and never stopping with hot brakes.
The rear calipers have an electric parking brake motor. They are unforgiving in exactly one way: the piston must not be pushed until the internal screw has been retracted.
The ball screw carries its load through point contacts at very high stress. If the piston is pressed while the screw is still extended, those point contacts take the full force and dent the raceway. That damage is permanent and shows up as a stiffer, notchy stroke, a C1110 code, or a dead motor.
Separately, the gearset inside the motor acts as a mechanical lock in one direction, so turning the piston cannot back the screw out — it just destroys the piston's anti-rotation feature and twists the dust boot.
Turning the shaft by hand leaves no position record, and you must re-learn nothing — the system re-calibrates when the parking brake is cycled. The real costs of Method B are mechanical: a fragile connector, an O-ring seal you disturb, and a blind operation with no feedback. If the Autel is available, use Method A.
After bedding or any hard braking, the rear rotors are hot. Apply the EPB and you clamp a hot pad against a stationary disc — the same pad-imprinting failure as the front. Park in P with the wheels chocked, and leave the parking brake off until everything has cooled down.
Data to read before, during, and after the job. Not sequential — look things up.
| Fastener | Torque | Confidence & note |
|---|---|---|
| Caliper bracket bolts (front, 17 mm, M12) | 80 ft-lb / 108 N·m | High — five sources agree. Not touched this session. |
| Wheel lug nuts (all four corners) | 80 ft-lb / 108 N·m | High — star pattern, two passes. |
| Front guide-pin bolt | ~25 ft-lb / 34 N·m | Low — low-torque floating fastener. Do NOT use 37 ft-lb (that is the Si caliper value). |
| Rear caliper bolts | 18 ft-lb / 24 N·m | Medium — community reference for this platform. |
| EPB actuator housing (2× 5 mm hex) | 5.9 ft-lb / 8 N·m | Medium — light fastener, over-torque cracks the housing. |
| Rotor retaining screws (M6×14, JIS #3) | 5–7 ft-lb / 7–9 N·m | Medium — not removed this session. M6: low torque or it strips. |
| Bleed screw | ~7 ft-lb / 10 N·m | Medium — only if bleeding. |
Bracket bolts: dry torque spec. No anti-seize, no grease — lubricant makes the same 80 ft-lb produce a higher preload and can stretch or snap the bolt. Clean the threads with a wire brush first; rust eats torque. Two bolts, alternating, in stages: hand-tight → 40 → 80.
| Item | Part / spec | Notes |
|---|---|---|
| Front pads | EBC DP51655NDX | Bluestuff NDX, μ 0.52, R90 legal, pre-scorched, stable to 550°C. One box = both front wheels. |
| Rear pads | R1 2600-1878-00 | Ceramic European, D1878 shape. Already owned. |
| Brake cleaner | Non-chlorinated ×2 | Blaster 20-BC ($5.80 at Home Depot) or CRC non-chlorinated. Never chlorinated. |
| Brake grease | High-temp silicone | Backing plates and pad ears only. A different product from anti-seize. |
| Anti-seize | Copper or nickel | Only for rotor retaining screws if they ever come out. Never on bracket threads. |
| Surface conditioning discs | RYOBI A911602 | 2″ backer with ¼″ shank + fine/medium/coarse discs. $27.22 at Home Depot. |
| Lint-free cloths | Several | Change cloth the moment it is loaded — a dirty cloth just moves the oil. |
| Gloves, eye protection, respirator | Nitrile + N95 | Brake dust contains metal particulate. Do not dry-brush it into the air. |
| Symptom | Likely cause | Action |
|---|---|---|
| Pedal goes to the floor | Pistons not seated / leak | Pump pedal 10–15×. If it does not firm up, or fluid disappears: do not drive. Find the leak. |
| Pulsation when braking | Disc thickness variation (front) or uneven transfer layer | If it appeared after bedding, the transfer layer is uneven — re-run the rotor prep and re-bed. If it persists, have the rotors measured for parallelity. It is not always an emergency. |
| Squeal at low speed, light braking | Pad ears dry, or missing grease on backing plate | Remove the pads, clean the bracket clips, re-grease backing plates and ears. Normal break-in squeal fades within a few hundred miles. |
| Grinding noise | Pad worn to backing plate, or a foreign object | Stop driving. Jack up, inspect. Grinding is metal-on-metal. |
| EPB warning light / C1110 / C1111 | Actuator connector not fully seated (most common), or a retract that went wrong | First, check the connector under the car at the rear calipers — push until it clicks. Then cycle the EPB. If the code persists, read all modules with the AP200. |
| Brake pulls to one side | One caliper dragging / pads not free in the bracket | Feel the wheels after a short drive — a dragging brake runs hot. Clean the bracket clips, verify pad float. |
| Soft/spongy pedal that fades | Old brake fluid boiling | Not caused by this job — but this is the trigger for a fluid change before the next track day. See below. |
Fill in and keep. This is your baseline for the next inspection.
