34 10 014 Adjusting handbrake

WARNING: This page is about a different car, the 2008 MINI Cooper, 2007 MINI Cooper, 2006 MINI Cooper, and 2005 MINI Cooper. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

For Special Tool identification, see BRAKES - SPECIAL TOOLS - COOPER (1.6L) R50/W10 .

Special Tools Required:

34 6 301
34 6 306
34 6 307
34 6 308

Perform inspection in the following manner:

When 1st ratchet is engaged, no braking force should be exerted.

The difference in wheel circumferential forces between the left and right wheels may deviate by max. 30 % from the greater value (measured on brake analyzer).

In event of larger deviations of wheel circumferential force: readjust handbrake.

Braking with locked wheels must be possible with the handbrake.

The handbrake must be readjusted if the actuation stroke is greater than 6 teeth.

NOTE: The handbrake can only be adjusted correctly when the parking brake Bowden cables and all moving handbrake parts are free to move and fully operational. Basic handbrake adjustment is necessary:

When replacing rear wheel brake pads.
When replacing brake disks.
In event of excessive actuation stroke (6 teeth).
When replacing parking brake Bowden cables.
When replacing handbrake lever.

Setting Instruction For Parking Brake Bowden Cables

Release gaiter (1) of parking brake lever from clip.

Release self-locking nut (2) until the load on the Bowden cable has been relieved completely.

Screw in adjusting nut on handbrake lever until a gap (3) of 2-3 mm between handbrake actuating lever (2) and cotter pin (1) is set at brake calipers.

IMPORTANT: Observe following sequence:

Release adjusting nut on handbrake lever completely.
Adjust adjusting nut on handbrake lever as shown above.
Apply handbrake lever three times.
Press brake pedal to floor at least three times so that air gap can be set.
Carry out operational check.

Checking Adjustment On Brake Analyzer

0th tooth (handbrake released): Vehicles with manual transmission: Shift lever in neutral position. Vehicles with automatic transmission: Selector lever in "N" position wheel circumferential force <=100 N.

1st Tooth: No increase in braking force with regard to 0th tooth. Indicator lamp can be lit.

2nd Tooth: An increase in braking force must occur, indicator lamp must be lit.

3rd Tooth: Increase In Braking Force.

4th Tooth: Wheel circumferential force per wheel: 700 N to 1300 N.

(Must be achieved in the 4th tooth at the latest).
