Warnings
⚠️SAFETY-CRITICAL: Brake system failure can result in loss of vehicle control, causing severe injury or death. If you are uncertain about any step, have this work performed by a qualified technician.
⚠️Never reuse old brake fluid. Contaminated or degraded brake fluid can cause complete brake failure.
⚠️Do not allow brake fluid to contact painted surfaces - it will permanently damage paint. Keep rags and cleaner available.
⚠️After completing this repair, pump the brake pedal multiple times before attempting to drive. Test brakes at low speed in a safe area before normal operation.
⚠Brake dust may contain asbestos or other harmful materials. Do not blow dust with compressed air. Use brake parts cleaner and allow dust to settle into drip pan.
⚠Inspect all brake components carefully during disassembly. Replace calipers entirely if cylinders are scored, pitted, or corroded beyond light surface rust.
ℹ️This procedure assumes brake lines will NOT be disconnected. If lines are disconnected, the entire system must be bled according to manufacturer procedure.

Parts
- Front brake caliper rebuild kit (seals, dust boots, piston seals) × 2 — Use OEM or quality aftermarket kit specific to 2012-2017 Camry
- DOT 3 brake fluid × 1 — Use OEM specification
- Copper crush washers for banjo bolt (if removing brake line) × 2 — Use OEM specification
Fluids
- DOT 3 Brake Fluid — 1 qt
Preparation
- Park vehicle on level ground and chock rear wheels securely
- Loosen front wheel lug nuts while vehicle is on ground, but do not remove
- Lift front of vehicle with floor jack and support securely on jack stands placed on designated lift points
- Remove front wheels completely
- Place drip pan under work area to catch brake fluid
- Open brake fluid reservoir cap slightly to allow fluid movement during piston retraction (monitor level throughout procedure)
- Clean exterior of brake calipers, brackets, and surrounding area with brake parts cleaner to prevent contamination
Procedure
- 1Remove caliper from bracketRemove the two caliper slide pin bolts (17mm) securing the caliper to the bracket. Support the caliper - do not let it hang by the brake hose. Suspend caliper from suspension using wire or bungee cord. Do NOT disconnect the brake line at this time unless absolutely necessary.Torque specCaliper Slide Pin Bolts35 Nm (26 lb-ft)
- 2Remove brake pads and hardwareRemove brake pads from the caliper bracket. Remove pad shims and anti-rattle clips. Inspect all hardware for wear or damage - replace if necessary. Set aside in clean area for reinstallation.
- 3Drain caliper and secure for disassemblyIf brake line was not disconnected, carefully clamp the flexible brake hose with proper brake hose clamp to minimize fluid loss. Open bleeder screw and allow caliper to drain into drip pan. If attempting to rebuild without removing caliper from vehicle, place rags underneath to protect components from brake fluid. For easier access, consider removing caliper bracket from knuckle using two 17mm bolts.⚠Use only proper brake hose clamps designed for this purpose. Do not use locking pliers or vise grips as they will damage the hose internally.Torque specBleeder Screw10 Nm (7 lb-ft)Bracket Bolts102 Nm (75 lb-ft)
- 4Remove piston from caliper bodyRemove dust boot retaining ring if present. Using compressed air applied carefully to the brake fluid inlet port (or bleeder port), gently push the piston out of the caliper bore. Use low pressure and control piston exit with a rag - do not allow piston to shoot out forcefully. Alternatively, if caliper is still connected to hydraulic system, carefully pump brake pedal while watching piston - have assistant stop when piston begins to emerge.⚠️PINCH HAZARD: Piston can be expelled with significant force. Keep fingers clear of piston path. Use low air pressure (20-30 psi maximum) and control with thick rag.⚠If piston will not move, caliper bore may be seized. Do not force - caliper may require replacement.
- 5Remove seals and inspect caliper boreUsing plastic or wooden pick (never metal), carefully remove the piston seal from the groove inside the caliper bore. Remove any remaining dust boot material. Thoroughly inspect the caliper bore for scoring, pitting, rust, or corrosion. Minor staining is acceptable, but any scoring or pitting that can be felt with a fingernail indicates the caliper must be replaced, not rebuilt. Inspect piston for chrome plating damage, scoring, or corrosion - replace piston or entire caliper if damaged.⚠CRITICAL INSPECTION POINT: Any damage to the caliper bore or piston sealing surface will cause leaks and brake failure. When in doubt, replace the caliper.
- 6Clean all components thoroughlyClean caliper bore, piston, and all internal passages with brake parts cleaner and lint-free cloths. Use wire brush on external caliper surfaces only - never inside bore. Flush all passages including bleeder port and brake line port. Dry with compressed air if available, or allow to air dry completely. Ensure no lint, debris, or cleaning residue remains.⚠Any contamination in the hydraulic system can cause brake failure. Cleanliness is critical.
- 7Install new sealsCoat new piston seal lightly with clean DOT 3 brake fluid. Carefully install seal into the groove in the caliper bore, ensuring it seats properly all the way around with no twists or folds. Verify seal is fully seated below the surface of the groove.
- 8Install piston and dust bootCoat piston and caliper bore lightly with clean DOT 3 brake fluid. Install new dust boot onto piston groove first, or per rebuild kit instructions. Carefully insert piston into bore, being extremely careful not to damage or dislodge the piston seal. Push piston in squarely - do not cock at an angle. Push piston fully into bore using appropriate tool. Seat dust boot into caliper body groove, ensuring it is properly positioned all the way around.⚠Do not force piston if resistance is felt. Remove and inspect for seal displacement or misalignment. Damaged seals will cause immediate brake failure.
- 9Inspect and lubricate slide pinsRemove caliper slide pins from bracket if not already removed. Clean pins thoroughly with brake parts cleaner. Inspect pins and pin boots for wear, cracking, or damage - replace if worn. Apply thin coat of high-temperature silicone brake grease to slide pin shafts. Reinstall pins into bracket with new boots if supplied in kit.ℹ️Do not use petroleum-based grease. Only use silicone brake grease specified for brake applications.
- 10Reassemble caliper to bracketIf caliper bracket was removed, reinstall to steering knuckle and torque bracket bolts to specification. Install brake pad hardware, shims, and pads into bracket. Position caliper over brake pads and install slide pin bolts with silicone brake grease on threads and contact surfaces. Torque slide pin bolts to specification.Torque specBracket Bolts102 Nm (75 lb-ft)Caliper Slide Pin Bolts35 Nm (26 lb-ft)
- 11Bleed brake systemIf brake line was not disconnected, remove hose clamp and bleed caliper at bleeder screw using appropriate bleeding procedure. If line was disconnected, entire system must be bled per manufacturer procedure. Attach clear tube to bleeder screw with other end submerged in clean brake fluid. Have assistant pump brake pedal several times and hold pressure. Open bleeder screw, allow fluid and air to escape, close bleeder before pedal reaches floor. Repeat until no air bubbles appear and fluid is clean. Torque bleeder screw to specification.⚠️All air must be purged from the system. Air in brake lines causes spongy pedal and reduced braking force.Torque specBleeder Screw10 Nm (7 lb-ft)
- 12Check fluid level and inspect for leaksFill brake fluid reservoir to MAX line with fresh DOT 3 brake fluid. Pump brake pedal multiple times to seat pads and verify firm pedal. Inspect all caliper connections, bleeder screws, and brake line connections for leaks. Wipe all surfaces clean and verify no fluid seepage after pumping pedal 20-30 times.⚠️Any brake fluid leakage indicates improper assembly or damaged components. Do not drive vehicle if leaks are present.
- 13Reinstall wheelsReinstall wheels and hand-tighten lug nuts in star pattern. Lower vehicle to ground. Torque lug nuts to specification in star pattern in multiple passes.Torque specWheel Lug Nuts140 Nm (103 lb-ft)
Reassembly
- Ensure all torque specifications have been met, especially caliper bracket bolts, slide pin bolts, and lug nuts
- Verify brake fluid level is at MAX line in reservoir and cap is securely tightened
- Verify no tools or parts have been left in wheel well or under vehicle
- Repeat entire procedure for opposite side front caliper to ensure balanced braking performance
Verification
- With vehicle still raised or in safe location, pump brake pedal 20-30 times. Pedal should become firm and hold pressure without sinking
- Start engine and verify brake pedal remains firm with power assist active. Pedal should not sink toward floor under steady pressure
- Visually inspect all caliper connections, bleeder screws, and brake lines for any fluid leakage
- Test drive vehicle in safe area at low speed (under 10 mph) and verify brakes respond normally without pulling to one side
- Perform several moderate brake applications from 20-30 mph to seat pads and verify proper operation
- After first 50-100 miles, recheck brake fluid level and inspect for leaks. Retorque wheel lug nuts after first drive
- Monitor brake pedal feel for first several days. Any sponginess, sinking pedal, or unusual behavior requires immediate inspection
