🔧 RX350 - Front Brake Pad Replacement

You’ll remove the front wheels, swing the front brake calipers out of the way, compress the caliper pistons, and install new pads (plus the pad hardware). This restores braking performance and prevents metal-to-metal damage when pads get thin.

Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours

⚠️ Safety & Precautions

• 🛑 Work on level ground; support the SUV on jack stands, not the jack.
• 🛑 Do not press the brake pedal while a caliper is off the rotor.
• 🛑 Brake dust is harmful—avoid blowing it with compressed air; use brake cleaner.
• 🛑 Watch brake fluid level while compressing pistons; siphon excess if it nears overflow.
• 🛑 Keep grease off pad friction material and rotor surfaces.

📋 Before You Begin

• Park on level ground, shift to Park, and set the parking brake.
• Place wheel chocks behind the rear wheels.
• Crack the front lug nuts loose slightly using a 21mm socket and breaker bar before lifting.
• Open the hood and locate the brake fluid reservoir; keep the cap loosely set on top (don’t remove it completely unless needed).
• Assumption: front rotors are reusable and not being replaced.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front end

• Use a floor jack to lift at the front jacking point.
• Set the SUV onto jack stands and lightly shake it to confirm it’s stable.
• Remove the front wheels using a 21mm socket and ratchet.

Step 2: Inspect and prep the caliper

• Turn the steering wheel to give yourself room (left side: turn wheel right; right side: turn wheel left).
• Check the brake hose routing and make sure it won’t be stretched during the job.
• Spray the caliper/pad area with brake parts cleaner and let it drip into a drain pan.

Step 3: Remove the caliper (do not hang by the hose)

• Remove the two caliper slide pin bolts using a 14mm socket and ratchet.
• Lift the caliper off the rotor. If it’s tight, gently pry with a flat-blade screwdriver.
• Support the caliper with a bungee cord or mechanic’s wire to the strut spring.

Step 4: Remove old pads and hardware

• Slide the old pads out of the bracket by hand.
• Remove the stainless pad clips (abutment clips). Use a flat-blade screwdriver if needed.
• Clean the bracket pad “tracks” with a wire brush and brake parts cleaner.

Step 5: Compress the caliper piston

• Check the brake fluid reservoir under the hood; remove fluid with a turkey baster or fluid syringe if it’s near the MAX line.
• Place one old pad against the piston face, then compress the piston slowly using a C-clamp (6" minimum).
• A “disc brake piston compressor” is a tool that pushes the piston in evenly; it’s safer and easier than forcing it crooked.
• Go slow—fast compression can overflow fluid.

Step 6: Service slide pins (recommended)

• Pull the slide pins out of the caliper bracket by hand.
• Wipe old grease off, then apply a thin coat of brake caliper grease (silicone).
• Reinsert the pins and confirm they move smoothly.

Step 7: Install new hardware and pads

• Install new abutment clips from the front brake pad hardware kit onto the bracket.
• Apply a very thin film of brake caliper grease (silicone) where the pad ears contact the clips (metal-to-metal contact points only).
• Install the new pads into the bracket, matching inner/outer orientation (wear indicator typically goes on the inner pad).
• If included/desired, apply brake anti-squeal compound to the pad backing plates (not the pad friction surface).

Step 8: Reinstall the caliper and torque fasteners

• Lower the caliper over the new pads.
• Install the caliper slide pin bolts using a 14mm socket.
• Torque to 34 Nm (25 ft-lbs) using a torque wrench.

Step 9: Reinstall wheels and torque lug nuts

• Reinstall the wheels and hand-thread lug nuts.
• Lower the SUV off the stands using the floor jack.
• Tighten lug nuts in a star pattern using a 21mm socket and torque wrench.
• Torque to 103 Nm (76 ft-lbs).

Step 10: Restore pedal feel before driving

• With the engine OFF, press the brake pedal slowly 10-15 times until it feels firm.
• Check brake fluid level and top off only if needed (correct DOT fluid as specified on the reservoir cap).
• Do a slow test roll in a safe area and confirm normal stopping.

✅ After Repair

• Do a short road test: 5-10 gentle stops from 25-35 mph, leaving space between stops.
• Listen for grinding or constant squeal; recheck pad seating and hardware if noises persist.
• Recheck brake fluid level after the test drive.
• Avoid hard braking for the first 200 miles.
