🔧 SRX - Front Brake Pads & Rotor Replacement

You’ll remove the front wheels, take the caliper and bracket off, replace the rotor, then install new pads and reassemble everything with the correct torque. New rotors are important because old rotors can be worn, grooved, or warped and can ruin new pads quickly.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

Assumption: Your SRX has the common 2-piston front calipers; bolt sizes may vary slightly by brake package.

⚠️ Safety & Precautions

• ⚠️ Work on a flat, solid surface; never rely on a jack alone.
• ⚠️ Support the vehicle with jack stands (rated 3-ton minimum) before removing wheels.
• ⚠️ Do not let the brake caliper hang by the rubber hose; it can damage the hose.
• ⚠️ Brake dust is unhealthy—use brake cleaner and avoid blowing dust with compressed air.
• ⚠️ Keep brake fluid off paint; it can damage the finish.
• ⚠️ Battery disconnect is not required for this job.

📋 Before You Begin

• Park on level ground, put the shifter in P, and set the parking brake.
• Place wheel chocks behind the rear wheels.
• Open the hood and locate the brake fluid reservoir.
• Check the reservoir level now—when you compress the caliper pistons later, the fluid level can rise.
• Tip: If the reservoir is very full, remove a little fluid.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen lug nuts and lift the front

• Use a 21mm socket and breaker bar to loosen the front lug nuts about 1 turn (do not remove yet).
• Use a floor jack to lift the front of the SRX at the proper front jack point.
• Set the SRX down onto jack stands securely.
• Remove the lug nuts with the 21mm socket and remove the wheel.

Step 2: Inspect and prep the caliper

• Turn the steering so you can easily access the caliper.
• Use safety glasses and spray brake cleaner to wash off dust and dirt.
• Use a flat-blade screwdriver to gently pry the pad away from the rotor a tiny amount (this helps caliper removal).

Step 3: Remove the caliper slide bolts

• Locate the two caliper slide bolts on the back of the caliper.
• Use a 13mm socket and ratchet to remove the caliper slide bolts.
• Lift the caliper off the bracket.
• Hang the caliper using a mechanic’s wire hook or bungee cord so the hose is not stressed.
• Tip: “Slide bolts” are the smaller bolts on the caliper.

Step 4: Remove old brake pads and hardware

• Slide the old pads out of the bracket by hand.
• Remove the old stainless pad clips (hardware) from the bracket.
• Use a wire brush to clean the bracket pad-clip “rails” (where the clips sit).
• Spray with brake cleaner and wipe with shop towels.

Step 5: Remove the caliper bracket

• Remove the two large caliper bracket bolts on the back of the steering knuckle.
• Use an 18mm socket and breaker bar to loosen and remove them (they are usually tight).
• Set the bracket aside.

Step 6: Remove the rotor

• If the rotor is stuck to the hub, spray the hub/rotor center area with brake cleaner and let it soak a minute.
• Tap the rotor “hat” area with the side of the breaker bar (controlled hits) while pulling outward to break it free.
• Remove the rotor.
• Use a wire brush to clean rust off the hub face so the new rotor sits flat.
• Tip: A dirty hub can cause brake pedal pulsation.

Step 7: Install the new rotor

• Spray both sides of the new rotor with brake cleaner to remove the protective shipping oil.
• Slide the rotor onto the hub.
• To hold it in place, thread on one lug nut by hand (use a lug nut backwards) and snug it lightly with a 21mm socket.

Step 8: Reinstall the caliper bracket

• Position the bracket back over the rotor.
• Start the bracket bolts by hand to avoid cross-threading.
• Use an 18mm socket and torque wrench to tighten the bracket bolts: Torque to 200 Nm (148 ft-lbs).

Step 9: Install new pad hardware and pads

• Install the new stainless pad clips into the bracket by hand (they snap into place).
• Apply a very thin film of high-temp silicone brake grease where the pad ears contact the clips.
• Slide the new pads into the bracket.
• Tip: Keep grease off pad friction material.

Step 10: Compress the caliper pistons

• Place one old brake pad against the caliper pistons to spread the force.
• Use a C-clamp brake piston tool to slowly press the pistons back into the caliper.
• Check the brake fluid reservoir while compressing; if it rises too high, remove a little fluid into a drain pan.
• Tip: Slow and steady prevents seal damage.

Step 11: Reinstall the caliper

• Place the caliper over the new pads and align the slide bolt holes.
• Install the slide bolts by hand first.
• Use a 13mm socket and torque wrench to tighten: Torque to 38 Nm (28 ft-lbs).

Step 12: Reinstall wheel and torque lug nuts

• Remove the temporary lug nut holding the rotor.
• Install the wheel and hand-thread all lug nuts.
• Lower the SRX off the jack stands with the floor jack.
• Use a 21mm socket and torque wrench to torque lug nuts in a star pattern: Torque to 190 Nm (140 ft-lbs).

Step 13: Repeat on the other front side

• Repeat Steps 1–12 for the other front wheel.
• Tip: Brakes should be replaced in pairs.

✅ After Repair

• With the engine OFF, press the brake pedal slowly 10–15 times until it feels firm (this seats the pistons to the pads).
• Check the brake fluid level and top off with DOT 3 only if needed.
• Start the engine and confirm the brake pedal feels normal (not sinking).
• Test drive at low speed first; confirm no pulling, grinding, or warning lights.
• Bed-in (break-in) the pads: make 6–10 medium stops from ~35 mph down to ~5 mph, letting brakes cool a bit between stops; avoid hard stops for the first 200 miles.
• Re-check lug nut torque after 25–50 miles with a torque wrench.
