WM 467919 Removing and installing brake cable for foot-operated parking brake (rear)
Information
Important notes
Rear brake cable -E- means: from the deflector under the centre console -D- to the Quickfit lock in the brake drum on the rear wheel.
Component arrangement - foot-operated parking brake
Information
- When performing various tasks on the rear axle, e.g. removing and installing the wheel bearing housing, the brake cable only needs to be detached without removing the entire brake cable. Refer to the description at the end of the installation section, => 467919 Removing and installing brake cable for foot-operated parking brake (rear) - section on "detaching and fastening", for this purpose.
Removing brake cable for foot-operated parking brake (rear)
1. Move control pedal of the foot-operated parking brake to the zero position. To do this, pull the release lever on the dashboard.
2. Remove cover in the footwell => 702219 Removing and installing cover under dashboard - section on "Removing".
3. Fix the adjustment device using an auxiliary pin (max. 3.5 mm in diameter) -see figure-. In other words: press the adjustment device together -arrow- until the assembly bores are covered and the auxiliary pin can be inserted => 466019 Removing and installing actuator for foot-operated parking brake. The cover on the actuating mechanism does not need to be removed. The auxiliary pin can be inserted through the cover.

4. Remove centre console => 681719 Removing and installing centre console - section on "Removing".
5. Raise the vehicle => 40 Lifting the vehicle.
6. Remove the relevant rear wheel => 440519 Removing and installing wheel - section on "Removing".
7. Pull the balancing clip of the deflector completely back, against the direction of travel, and loosen the small fastening screw.

8. To remove and disengage the ball head(s) of the cables, the nut on the threaded rod -arrow- can be loosened by a few turns. (Note the number of turns. Mark the nut, if necessary).

9. Push the ball head out of the balancing clip of the deflector in the direction of the arrow -see figure- and remove it sideways. Press the sleeve of the cable in the interior (two plastic lugs) gently together and push through to the rear, against the direction of travel.

10. Remove the sheetmetal clips -see figure- for the parking-brake cables at the fuel tank (underbody) with a screwdriver.
Brake cable routing
11. Pull the relevant cable out to the rear.
Information
- The screw plug -arrow- of the brake disc obscures the view of the Quickfit. The Quickfit is positioned at approx. 3 o'clock to the right and approx. 9 o'clock to the left.
Screw plug for adjusting the duo-servo
- The brake discs do not have to be removed to disengage the brake cables.
12. Remove the screw plug -arrow- at the brake disc.
13. Remove the brake cable. Do not loosen the circlip. To do this, insert a screwdriver between the sleeve of the brake cable and the wheel bearing housing -see figure-.
Removing brake cable from wheel carrier
14. Pull the sleeve of the cable -arrows- as far as possible out of the wheel bearing housing.
15. Push the cable gently into the brake drum. Use a small screwdriver -see figure- inserted through the brake disc opening to press the safety spring and hexagon on the spreading lever upwards and at the same time pull the brake cable out of the brake drum.

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 figure- can be used as compensation.
Brake cable ring grooves
- In this case, loosen the circlip -see figure- 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.
Loosening circlip on brake cable
- 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 figure- 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 figure- from the actuating mechanism of the foot-operated parking brake.

6. Perform a function test. Set the brake shoes to the basic setting, if necessary => 468316 Adjusting foot-operated parking brake.
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 => 681719 Removing and installing centre console - section on "Installing".
8. Install cover in the footwell => 702219 Removing and installing cover under dashboard - section on "Installing".
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.
11. Fit the wheel => 440519 Removing and installing wheel - section on "Installing" and tighten to the specified tightening torque.
Disengaging and engaging brake cable (partial removal)
Disengaging brake cable
1. Move control pedal of the foot-operated parking brake to the zero position. To do this, pull the release lever on the dashboard.
