Brake Pads
Special tools, testers and auxiliary items required
• Torque Wrench (V.A.G 1331)
• Piston Resetting Tool (T10145)
Removing
When removing, mark brake pads that will be used again. Install in the same position, otherwise braking effect will be uneven!
- Remove wheels.
- Pry brake caliper retaining spring out of brake pad retaining spring with screwdriver. To do this, place screwdriver between both retaining springs - close-up -.
- Secure brake caliper retaining spring with a cloth when doing this so that it cannot jump away.
- Separate the connector - 1 - for brake pad wear indicator.
- Remove caps - arrows -.
- Loosen both guide pins - arrows - and remove from brake caliper.
- Remove brake caliper and secure with wire so that the weight of the brake caliper does not burden or damage the brake hose.
- Remove brake pads from brake caliper.
Cleaning:
CAUTION!
Do not blow brake system using compressed air, the dust produced is harmful to health!
- Thoroughly clean contact surfaces for brake pads at brake carrier, remove corrosion.
- Clean brake caliper.
Use only appropriate solvents for cleaning brake caliper.
Installing
Before pressing piston 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.
- Press piston back.
- Insert inner brake pad - arrows - with retaining spring in brake caliper (piston).
- Set outer brake pad - 2 - with retaining springs into brake caliper.
- Place brake caliper with brake pads on brake carrier.
- Tighten brake caliper to brake carrier using both guide pins.
- Install both protective caps.
- Insert brake caliper retaining spring in brake pad retaining spring and press under brake carrier.
- Connect brake pad wear indicator connector.
- Install wheels.
Tightening specification for wheel bolts.
• After replacing brake pads, depress brake pedal firmly several times with vehicle stationary so that the brake pads are properly seated in their normal operating position.
• Check brake fluid level after replacing brake pad.
