🔧 ES350 - Front Brake Pads & Rotor Replacement

You’ll remove the front wheels, take off the brake caliper and bracket, replace the rotor, then install new pads/hardware and reassemble. This restores braking performance and prevents vibration/pulsation from worn or warped rotors.

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

⚠️ Safety & Precautions

• 🛑 Support the car with jack stands—never work under a car held only by a jack.
• 🛑 Brake dust is unhealthy—wear a mask and avoid blowing dust with compressed air.
• 🛑 Don’t let the caliper hang by the brake hose—support it with a hook.
• 🛑 Brake fluid can damage paint—wipe spills immediately.
• 🛑 Pump the brake pedal before driving—first press may go to the floor.

📋 Before You Begin

• Park on level ground, set the parking brake, and place wheel chocks behind the rear wheels.
• Loosen the front lug nuts about 1 turn using a 21mm socket and breaker bar before lifting.
• Open the hood and locate the brake fluid reservoir. Leave the cap loosely set on top (don’t remove it completely). This helps when you push the pistons back.
• Place a drain pan under the brake area—brake cleaner runoff gets messy.
• Assumption: Standard single-piston floating front calipers (most common on the ES350).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front of the car

• Use a floor jack (rated 3-ton minimum) to lift the front at the proper front jacking point.
• Place jack stands (rated 3-ton minimum) under the proper support points and lower the car onto them.
• Remove the lug nuts with a 21mm socket and 3/8" drive ratchet, then remove both front wheels.

Step 2: Remove the caliper (do not stretch the hose)

• Turn the steering wheel to give yourself room (left for right side, right for left side).
• Remove the two caliper slide pin bolts using a 14mm socket and 3/8" drive ratchet.
• Lift the caliper off the pads and bracket.
• Hang the caliper using a brake caliper hanger hook so the brake hose is not supporting weight.

Step 3: Remove the old pads and hardware

• Pull the pads out of the bracket by hand. If stuck, gently pry with a flathead screwdriver.
• Remove the pad clips/hardware from the bracket.
• Spray the bracket with brake cleaner spray and scrub rust with a wire brush.
• Tip: Clean metal-to-metal contact points well.

Step 4: Remove the caliper bracket

• Remove the two caliper bracket bolts using a 17mm socket and 1/2" drive breaker bar.
• Set the bracket aside.

Step 5: Remove the rotor

• Pull the rotor straight off. If it’s seized with rust:
• Strike the rotor “hat” area (the thick center area) with a rubber mallet while rotating the rotor.
• Clean the wheel hub face (where the rotor sits) using brake cleaner spray and a wire brush.
• Tip: A clean hub helps prevent brake pulsation.

Step 6: Install the new rotor

• Spray both sides of the new rotor with brake cleaner spray to remove shipping oil.
• Install the rotor onto the hub.
• To hold it square while you work, thread on one lug nut by hand (use your removed lug nut).

Step 7: Reinstall the bracket and torque it

• Reinstall the caliper bracket bolts using a 17mm socket and 1/2" drive ratchet.
• Torque to 107 Nm (79 ft-lbs) using a 1/2" drive torque wrench.

Step 8: Install new hardware and pads

• Install new pad clips/hardware onto the bracket by hand.
• Apply a thin layer of brake grease (silicone or synthetic) to the bracket “pad ears” contact points (where the pads slide).
• Install the new pads into the bracket.
• Tip: Pads must slide freely in the clips.

Step 9: Compress the caliper piston

• Remove the brake reservoir cap fully if needed and watch the fluid level.
• Use a C-clamp (6" minimum) to slowly press the piston back into the caliper.
• A C-clamp is a screw clamp that pushes the piston in evenly—go slow to avoid damage.
• If brake fluid rises near the top, remove some with a clean absorbent towel (don’t spill).

Step 10: Reinstall the caliper and torque the slide bolts

• Set the caliper over the new pads.
• Install the slide pin bolts using a 14mm socket and 3/8" drive ratchet.
• Torque to 34 Nm (25 ft-lbs) using a 3/8" drive torque wrench.

Step 11: Reinstall wheels and torque lug nuts

• Reinstall both wheels and hand-thread lug nuts.
• Lower the car using the floor jack (rated 3-ton minimum).
• Tighten lug nuts in a star pattern using a 21mm socket.
• Torque to 103 Nm (76 ft-lbs) using a 1/2" drive torque wrench.

✅ After Repair

• With the engine OFF, pump the brake pedal 10-15 times until it feels firm.
• Check brake fluid level and top off with brake fluid (DOT 3) if needed.
• Start the engine and confirm the pedal feels normal (it may drop slightly with vacuum assist).
• Test brakes at low speed first in a safe area.
• Bed-in (break-in) the pads: make 6-10 medium stops from ~40 mph down to ~10 mph, with light driving between stops to cool. Avoid hard panic stops for the first 200 miles.
• Listen for abnormal scraping and recheck lug nut torque after 25-50 miles.
