Brake pads, removing and installing
Removing
NOTE:
- When removing, mark brake pads that will be used again. Install in the same position, otherwise braking effect will be uneven!
- Observe the direction of rotation when installing brake disc arrow on brake disc and installed location left or right
- Raise vehicle.
- Remove wheels.
- Secure brake disc using a wheel bolt - arrow -.
- Using screwdriver, pry off brake pad retaining spring from brake caliper housing and remove.
NOTE:
- Spring is tensioned, protect with a glove or cloth.
- Disconnect brake wear indicator connector - arrow -.
- Release connector from retainer using a screwdriver and simultaneously turn connector 90°
- Pull connector out upward and unhook line
- Unhook brake line from retainer
- Remove caps - 1 -.
- Remove both guide pins from brake caliper.
- Remove brake caliper housing and set aside so that the weight of the brake caliper does not burden or damage brake hose.
- Remove brake pads from brake caliper housing or from brake carrier.
NOTE:
- The brake pad with wear indicator sits inside.
- Brake carrier must be removed to replace brake pads.
Clean brake caliper with mineral spirits exclusively.
Installing
- Press both pistons back.
NOTE:
- Press piston back into caliper housing using resetting tool before inserting new brake pads. Before pushing back the piston, siphon some of the brake fluid out of the brake fluid reservoir. Otherwise, especially if reservoir has been topped off, fluid will overflow and cause damage.
CAUTION:
Brake fluid is poisonous. NEVER siphon brake fluid with your mouth!
Fig 9: Setting Brake Pad With Retaining Spring And Wear Indicator Into Brake Caliper Housing (Piston)
- Set brake pad - arrows - with retaining spring and wear indicator into brake caliper housing (piston).
- Set outer brake pad - 2 - onto brake caliper.
NOTE:
- Insert brake pads into brake caliper and mount them together onto brake carrier and brake disc.
- Attach brake caliper housing to brake carrier and fasten guide pins to 30 Nm.
- Install both protective caps.
- Make sure that the brake hose is installed free of twists.
- Install retaining spring in brake caliper housing.
- Hook in brake line
- Connect connector for wear indicator and hook line into dust cap and cover.
- Install wheels → 44 - Wheels, Tires and Wheel Alignment
NOTE:
- After hooking into both studs, the retaining spring must be pressed under brake carrier. If improperly installed, the wear of the outer brake pad cannot be adjusted, thereby increasing brake pedal travel.
- After installing brake pads, depress brake pedal several times firmly to properly seat brake pads in their normal operating position.
- Check brake fluid level, and fill if necessary.
