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.
- Using screwdriver, pry off brake pad retaining spring from brake caliper - arrow - and remove.
- 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 pad from brake caliper or from brake carrier.
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.
- Install outer brake pad on brake carrier.
- Insert inner brake pad with retaining spring in brake caliper (piston).
- Tighten brake caliper to brake carrier using both guide pins.
- Install both protective caps.
- Install retaining spring in brake caliper.
- Connect brake pad wear indicator connector.
- Install wheels.
• 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.
