With Pressure Bleeder


NOTE: Bleeding the brake system is described using Brake filling and bleeding units VAG 1869, US 1116 or equivalent.

CAUTION: Vehicles with ABS/EDL:
^ Ensure that a filling pressure of 1 bar (14.5 psi) is not exceeded when filling with brake fluid using brake filling and bleeding units VAG 1869, US 1116 or equivalent.
^ If the filling pressure exceeds 1 bar (14.5 psi) it cannot be guaranteed that the hydraulic unit is adequately bled.

NOTE:
^ Bleeding the braking system on vehicles with ABS is the same as for vehicles with conventional braking systems.
^ Only use new brake fluid conforming to US standard FMVSS 116 DOT4. Genuine VW brake fluid conforms to this specification.
^ Break fluid is poisonous. Also, due to its corrosive effect, brake fluid must not come into contact with paintwork.
^ Break fluid is hygroscopic, which means it absorbs moisture from the ambient air and it should therefore always be stored in airtight containers.

Special Tools And Workshop Equipment





- VAG 1869 Brake filling and bleeding unit or:
- US 1116 Brake filling and bleeding unit or:
- Equivalent

Procedure

NOTE: If the brake master cylinder has been replaced or removed, bleed the brake system first. To do this proceed as described in the work sequence "Bleeding brake system Without Pressure Bleeder.

- Connect brake filling and bleeding unit.
- Open bleed screws in specified sequence and bleed brake calipers.

Bleeding Sequence
1 Right rear brake caliper
2 Left rear brake caliper
3 Right front brake caliper
4 Left front brake caliper


Vehicles With ABS or ABS/EDL

NOTE:
^ A test drive is recommended after bleeding brakes. During the test drive a braking action sufficient to activate the ABS must be performed at least once.
^ On vehicles with a brake pressure regulator move the regulator lever when bleeding the rear brakes.
