Brake Pads - Rear

This procedure covers the replacement of rear brake pads on a 2016-2021 Honda Civic with the 1.5L turbo engine, including caliper service and proper torque specifications.

Warnings

Tools required

Parts

• Rear brake pad set (left and right) × 1 — Use OEM Honda specification or equivalent
• Brake hardware kit (anti-rattle clips, shims) × 1 — Often included with quality pad sets

Fluids

• DOT 3 Brake Fluid — 0.25 qt

Preparation

1. Park vehicle on level, solid ground. Apply parking brake and place transmission in Park (automatic) or 1st gear (manual).
2. Loosen rear wheel lug nuts 1/4 turn while vehicle is still on the ground, but do not remove.
3. Lift rear of vehicle with floor jack at designated rear jacking point and secure on jack stands at reinforced pinch welds or frame rails.
4. Remove rear wheels completely and set aside.
5. Verify brake fluid level in master cylinder reservoir under hood. If near MAX line, remove some fluid with turkey baster or fluid pump to prevent overflow during piston compression.
6. Inspect brake rotors for excessive wear, scoring, or warping. Measure rotor thickness if calipers are available. Replace rotors if below service limit.

Procedure

1. 1

   Remove caliper slide pin bolts
   Locate the two caliper slide pin bolts on the rear of the caliper (typically 17mm). These bolts secure the caliper to the bracket and allow it to slide. Remove the lower slide pin bolt first, then remove the upper slide pin bolt. Keep these bolts clean and inspect the rubber boots for damage.

   Caliper Slide Pin Bolts30 Nm (22 lb-ft)
2. 2

   Pivot caliper upward and secure
   With both slide pin bolts removed, carefully pivot the caliper upward and away from the brake pads and rotor. The brake hose remains connected—do NOT let the caliper hang by the brake hose. Secure the caliper to the suspension or strut using wire or a bungee cord to prevent stress on the brake line.
   ⚠Never allow the caliper to hang by the brake hose, as this can damage the hose internally and cause brake failure.
3. 3

   Remove old brake pads and hardware
   Remove the inner and outer brake pads from the caliper bracket. Note the orientation and position of any anti-rattle clips, shims, or springs attached to the pads. Remove the old pad shims and anti-rattle clips from the caliper bracket. Inspect the caliper bracket for wear or damage.
   ℹ️Take photos before disassembly to reference pad orientation and hardware positioning during reassembly.
4. 4

   Clean caliper bracket and slides
   Use a wire brush to clean the pad abutment areas on the caliper bracket where the pads slide. Clean the caliper slide pins (removed from the bracket if necessary) with brake cleaner. Inspect the slide pin rubber boots for tears or damage—replace if compromised. Ensure all old grease and debris are removed from sliding surfaces.
   ⚠Do not use petroleum-based products on brake components. Use only brake cleaner and silicone brake grease.
5. 5

   Compress caliper piston
   Using a C-clamp or brake caliper compression tool, slowly compress the caliper piston(s) fully into the caliper bore. Position the clamp on the back of the caliper body and against the inner piston surface. Compress gradually and evenly. This creates clearance for the new, thicker brake pads.
   ⚠Watch the brake fluid reservoir as you compress the piston. If fluid overflows, stop and remove excess fluid before continuing.
   ℹ️Some rear calipers on certain Civic trim levels may have screw-in pistons requiring a special tool. Verify your caliper type—this procedure assumes standard compression-type pistons.
6. 6

   Install new pad hardware and lubricate
   Install new anti-rattle clips and shims onto the caliper bracket according to the orientation noted during removal or per the new pad kit instructions. Apply a thin layer of silicone brake grease to the caliper slide pins and to the pad abutment surfaces on the bracket (where pad ears contact the bracket). Do NOT get grease on the pad friction material or rotor surface.
   ⚠Use only silicone-based brake grease. Do not use standard grease, which can deteriorate in high heat and cause caliper seizure.
7. 7

   Install new brake pads
   Install the new inner and outer brake pads into the caliper bracket, ensuring they are properly seated in the anti-rattle clips and hardware. Verify that any wear indicators (squealer tabs) are positioned correctly according to manufacturer specifications—typically on the inner pad facing toward the piston. Confirm pads move freely in the bracket.
   ℹ️Pad wear indicators must be positioned correctly or they will not function. Verify orientation matches OEM specifications.
8. 8

   Reinstall caliper and slide pin bolts
   Remove the caliper from its suspended position and pivot it down over the new brake pads and rotor. Ensure the caliper piston aligns properly with the inner pad. Insert both caliper slide pin bolts and hand-tighten. Apply a small amount of silicone brake grease to the slide pin threads and rubber boots as specified. Torque both slide pin bolts to specification in a crisscross pattern.
   ⚠️Caliper slide pin bolts are CRITICAL fasteners. Under-torquing can allow the caliper to loosen during operation, causing brake failure. Use a calibrated torque wrench.

9. 9

   Repeat procedure for opposite side
   Repeat steps 1-8 for the opposite rear wheel to replace the brake pads on that side. It is essential to replace brake pads on both rear wheels simultaneously to maintain balanced braking performance.
   ⚠Always replace brake pads in axle sets (both rear wheels). Replacing only one side causes brake imbalance and unsafe handling.
10. 10

    Reinstall wheels and torque lug nuts
    Reinstall both rear wheels, threading lug nuts by hand to prevent cross-threading. Tighten lug nuts in a star pattern with a wrench while vehicle is still on jack stands, but do not torque to final specification yet. Lower vehicle completely to the ground so full weight is on the wheels. Using a calibrated torque wrench, torque all lug nuts to specification in a star pattern.
    ⚠Wheel lug nuts must be torqued to specification with vehicle weight on the ground. Improper torque can cause wheel detachment.

    Pump brake pedal and check fluid level
    With the vehicle in Park/Neutral and parking brake applied, pump the brake pedal slowly and firmly 10-15 times until it becomes firm and reaches normal height. This repositions the caliper pistons against the new pads. Check the brake fluid reservoir and top off to the MAX line with DOT 3 brake fluid if needed.
    ⚠️Do NOT attempt to drive the vehicle until the brake pedal is firm and normal. A soft or spongy pedal indicates air in the system or improperly installed components.

Reassembly

1. Verify all caliper slide pin bolts are torqued to specification (35 Nm / 26 lb-ft).
2. Verify all wheel lug nuts are torqued to specification (140 Nm / 103 lb-ft) in a star pattern with vehicle on the ground.
3. Confirm brake fluid reservoir is at proper level between MIN and MAX marks.
4. Ensure no tools or parts were left in the wheel well or brake area.

Verification

• Before driving, pump the brake pedal until firm. The pedal should feel solid and reach normal height within 10-15 pumps.
• Test brakes at low speed (under 10 mph) in a safe area to verify proper operation before normal driving.
• Listen for any unusual noises during initial brake application—light squealing may occur during pad break-in, but grinding or severe noise indicates a problem.
• Perform a controlled stop from 30-40 mph in a safe location to verify proper braking force and vehicle stability.
• After 50-100 miles of break-in driving, re-torque wheel lug nuts to specification and verify caliper slide pin bolt torque.
• New brake pads require a break-in period of approximately 200-300 miles for full performance. Avoid hard braking during this period when possible.
• Check for brake fluid leaks around caliper connections and verify fluid level has not dropped after test drive.
