Installing Brake Cable For Foot-Operated Parking Brake (Rear)

Information 

• On vehicles whose cables are still good but only stretched, the three ring grooves of the circlip -see Fig 1- can be used as compensation.

• In this case, loosen the circlip -see Fig 2- carefully (do not remove from the brake cable!) and move it by one ring groove. The circlip and cable are only available as an assembly. The settings must be the same on both sides.

• If the circlip has been damaged during removal/fitting (e.g. bent out of shape, circlip bent up), the entire cable must be replaced. 
• Use new sheetmetal clips. Pay attention to the installation position. 

1. Insert the end of the cable with the hexagon -see Fig 3- into the Quickfit on the wheel bearing housing. Push the cable at the other end (ball head) so far towards the wheel bearing housing that the hexagon engages audibly in the Quickfit. Ensure that it is well sealed.

2. Look through the brake disc opening with a small lamp to check that the end of the cable (hexagon) is seated correctly in the Quickfit.
3. Make sure that the circlip is seated correctly -arrow-  . (Shown here on the removed cable.)

4. Push the end of the cable with the ball head through the underbody and clip in the two plastic tabs. Mount the ball head in balancing clip in the passenger compartment. Fit the nut on the threaded rod using the number of turns noted previously. Ensure correct cable routing.
5. Remove the auxiliary pin -see Fig 5- from the actuating mechanism of the foot-operated parking brake.

6. Perform a function test. Set the brake shoes to the basic setting.

   Information 

   • Tolerances in the cables (different length right to left) can cause the balancing clip to be out of line when the foot-operated parking brake (FPB) is actuated. Press the FPB pedal gently until the cables are tensioned. Only then should you tighten the small screw (Torx T15) on the balancing clip by hand. 
   • Perform a function test. 
7. Fit centre console → Installing Centre Console .
8. Install cover in the footwell → Installing cover under dashboard .
9. Fit the screw plug on the brake disc.
10. To fit the brake cable correctly into the guides on the underbody and on the rear axle carrier, the brake cable must be taut. To do this, tug on the brake cable, against the direction of travel, in the cable sleeve area (thickening) on the rear axle carrier. This gives clearance between the brake cable and the cardan shaft.
