If old brake pads are being replaced with new ones, then it is necessary to check the brake rotor thickness for wear. Pay attention to the wear limit for the brake rotor thickness.

-- Check the brake rotor thickness. For the correct wear limit. Refer to FRONT BRAKES .

Use new bolts.

NOTE:

Before installing new brake pads, thoroughly clean the brake calipers of contaminants (grease-free). When doing so, pay particular attention to removing any remaining adhesive foil on outer brake pad contact surfaces.

Removing and installing.

Only use commercially available brake cleaner to clean the brake caliper housing.

CAUTION: Before pressing pistons into cylinder using piston resetting tool, brake fluid must be extracted from brake fluid reservoir. Otherwise, especially if reservoir has been topped off, fluid will overflow and cause damage.

WARNING: Brake fluid is poisonous. NEVER siphon brake fluid with your mouth!

-- Push the piston back using the Piston Resetting Tool T10145.

-- Install the balance spring -8- in the brake caliper.

WARNING:

Make sure the brakes are working correctly before driving the vehicle for the first time.

After installing, press the brake pedal several times firmly to properly seat brake pads in their normal operating position.

Maintain full braking pressure for approximately 20 seconds so that the shims can position themselves completely onto the brake pads.

Check brake fluid level after replacing brake pad.
