🔧 Canyon - Rear Brake Pad Replacement

Replacing the rear brake pads restores safe stopping power and prevents rotor damage when pads get thin. You’ll remove the rear caliper, swap the pads and hardware, compress the caliper piston, then reassemble and torque everything correctly.

Difficulty Level: Intermediate | Estimated Time: 1.5-3 hours

Assumption: Your Canyon has rear disc brakes with a cable-operated parking brake (no electronic EPB).

⚠️ Safety & Precautions

• 🛑 Work on level ground; chock the front wheels before lifting the rear.
• 🧯 Brake dust is harmful; use brake cleaner, not compressed air.
• 🧱 Always support the truck with jack stands; never rely on a floor jack alone.
• 🧵 Do not let the caliper hang by the brake hose; support it with a hanger.
• 🧴 Brake fluid can overflow when compressing pistons; keep rags handy and avoid spilling on paint.

📋 Before You Begin

• Park on a flat surface, shift to Neutral (manual trans), and set the parking brake.
• Chock both front wheels with wheel chocks.
• Crack the rear lug nuts loose 1/2 turn using a 22mm socket and breaker bar before lifting.
• Open the hood and loosen the brake fluid reservoir cap (do not remove it completely) so fluid can move as you compress pistons.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the rear

• Lift the rear with a floor jack (rated 3-ton minimum) at the approved rear lift point, then set the frame on jack stands (rated 3-ton minimum).
• Remove the rear wheels using a 22mm socket and ratchet.

Step 2: Locate the caliper and hardware

• Identify the caliper (the clamp that squeezes the rotor) and the caliper bracket (the larger mount the pads ride in).
• Turn the steering is not needed for rear; position yourself for clear access.

Step 3: Remove the caliper (not the bracket yet)

• Remove the two caliper slide pin bolts using a 13mm socket while holding the slide pin flats with a 15mm wrench.
• Lift the caliper off the bracket. Support it with a bungee cord so there is no strain on the hose.
• Tip: A flat screwdriver helps gently pry.

Step 4: Remove old pads and hardware

• Slide the inner and outer pads out of the bracket by hand; use a flat screwdriver if they’re stuck.
• Remove the stainless abutment clips (hardware) from the bracket using a flat screwdriver.
• Clean the bracket pad lands (where clips sit) with a wire brush, then spray with brake cleaner and let dry.

Step 5: Compress the caliper piston

• Place one old pad against the piston face, then use a C-clamp (6") to slowly press the piston fully back into the caliper.
• Watch the brake fluid reservoir while compressing. If it rises near max, stop and clean up any overflow immediately.

Step 6: Install new pad hardware and pads

• Install the new abutment clips from the rear brake pad hardware kit onto the bracket by hand (they snap into place).
• Apply a thin film of brake caliper slide pin grease (silicone) to the pad “ears” where they contact the clips (do not get grease on pad friction material).
• Install the new pads into the bracket in the same positions as removed.

Step 7: Service and reinstall slide pins, then reinstall caliper

• Pull the slide pins out (one at a time), wipe them clean, then apply fresh brake caliper slide pin grease (silicone).
• Reinstall the slide pins and boots fully seated by hand.
• Set the caliper back over the new pads, then install the slide pin bolts using a 13mm socket while holding with a 15mm wrench.
• Torque to 31 Nm (23 ft-lbs) for the rear caliper slide pin bolts.

Step 8: If you removed the caliper bracket (only if required)

• If your pads won’t come out without bracket removal (some rusted setups), remove the bracket bolts using an 18mm socket.
• Reinstall the bracket and Torque to 149 Nm (110 ft-lbs) for the rear caliper bracket bolts.
• Tip: Keep bolts organized left vs right.

Step 9: Reinstall wheels and torque lug nuts

• Reinstall the wheels and hand-thread lug nuts.
• Lower the truck off the jack stands (rated 3-ton minimum) using the floor jack (rated 3-ton minimum).
• Tighten lug nuts in a star pattern using a torque wrench (20-200 ft-lbs range).
• Torque to 190 Nm (140 ft-lbs) for the wheel lug nuts.

Step 10: Restore pedal and fluid level

• With the truck on the ground, slowly pump the brake pedal 10-15 times until it feels firm.
• Top off brake fluid if needed, then tighten the reservoir cap by hand.

✅ After Repair

• Start the engine and confirm the brake pedal stays firm.
• Do a slow test in a safe area: verify braking is smooth and straight.
• Bed-in the pads: make 6-10 moderate stops from ~30 mph down to ~5 mph, allowing a short cool-down between stops.
• Recheck for leaks, unusual smells, or dragging after the first short drive.
