🔧 TLX - Front Brake Pad Replacement

You’ll remove the front wheels, swing the front brake calipers up, swap the old pads for new ones, then reassemble and torque everything correctly. New pads restore safe stopping and prevent rotor damage when pads get thin.

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

Assumption: standard single-piston front calipers (most TLX Base).

⚠️ Safety & Precautions

• 🛑 Work on level ground and support the car with jack stands (never the jack alone).
• 🛑 Brake dust is unhealthy—avoid blowing it with air; use brake cleaner.
• 🛑 Do not let the caliper hang by the brake hose; support it with a hook/bungee.
• 🛑 Keep brake fluid off paint; it can damage the finish.
• 🛑 No battery disconnect is required for front pads on your TLX.

📋 Before You Begin

• 🧰 Park on level ground, turn the engine off, and chock the rear wheels with wheel chocks.
• 🧰 Crack the front lug nuts loose 1/4 turn using a 19mm socket and breaker bar before lifting.
• 🧰 Open the hood and locate the brake fluid reservoir; you may need to remove a little fluid if it gets too full after compressing pistons.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front end

• Place the floor jack (rated 3-ton minimum) under the front center jack point and lift.
• Set the car onto jack stands (rated 3-ton minimum) at the proper front support points.
• Give the car a gentle shake to confirm it’s stable before you work.

Step 2: Remove the front wheels

• Remove the lug nuts using a 19mm socket and 3/8" drive ratchet.
• Remove both front wheels and set them aside.

Step 3: Remove the caliper bolts and swing the caliper up

• Turn the steering to give yourself room to work (hand-push the tire hub if needed).
• Remove the two caliper slide-pin bolts using a 12mm socket and 3/8" drive ratchet.
• If the slide pin spins, hold it with a 14mm wrench while loosening the bolt.
• Lift/swing the caliper off the pads, then hang it from the strut spring using a brake caliper hanger hook.

Step 4: Remove old pads and hardware

• Pull the old inner and outer pads out by hand. If they’re stuck, gently pry with a flathead screwdriver (medium).
• Remove the pad abutment clips (hardware) from the bracket.
• Spray everything with brake parts cleaner and wipe with shop towels.

Step 5: Clean and prep the bracket

• Clean the pad contact areas on the bracket using a wire brush.
• Install the new abutment clips from the hardware kit.
• Apply a thin film of silicone brake lubricant where the pad “ears” slide on the clips. Thin coat only—don’t overdo it.

Step 6: Compress the caliper piston

• Before compressing, check the brake fluid reservoir level under the hood (it will rise).
• Place one old pad against the piston face, then use a C-clamp (6" minimum) to slowly press the piston back in. A C-clamp is a screw clamp that pushes the piston in evenly.
• Go slow and keep the piston straight; stop if it binds hard.

Step 7: Install the new pads

• Install the new inner and outer pads into the bracket.
• If your pad set includes wear indicators, install them in the same position as the originals.

Step 8: Reinstall the caliper and torque bolts

• Lower the caliper over the new pads.
• Install the caliper slide-pin bolts by hand first, then tighten using a 12mm socket and 3/8" drive ratchet.
• Torque to 34 Nm (25 ft-lbs) using a torque wrench (10–200 Nm range).

Step 9: Reinstall wheels and torque lug nuts

• Reinstall the wheels and hand-thread all lug nuts.
• Lower the car off the jack stands (rated 3-ton minimum) using the floor jack (rated 3-ton minimum).
• Tighten lug nuts in a star pattern with a torque wrench (10–200 Nm range): Torque to 127 Nm (94 ft-lbs).

✅ After Repair

• 🧪 Pump the brake pedal 10–15 times before driving until it feels firm (this seats the pistons against the new pads).
• 🧪 Check the brake fluid level and top off only if needed (use the correct DOT fluid listed on the reservoir cap).
• 🧪 Test at low speed first; confirm normal braking and no pulling or grinding.
• 🧪 Pad break-in (recommended): make 6–10 gentle stops from ~30–40 mph, with cool-down driving between stops.
• 🧪 Re-check for any leaks and re-torque lug nuts after 50–100 miles.
