Re: Grand Scenic Electronic Handbrake Stripdown Plus Photos

Try using a hand-made tool like the one from the first post (the last pictures).

If the cables move freely and appear OK then the pads may be causing the problem being worn right down, you may also need a special tool to release some slack cable from the control unit.
I made a tool up for that purpose from an old tyre lever and two lengths of 10mm screwed rod as in the photos. Fit to the cable as shown (with the handbrake off) ( See photos 29 & 30)

Screw up the nuts until the cable is tight. Operate the handbrake. Release the handbrake, there should be some slack on the cable now. Screw the nuts up to take up the slack. Repeat the process until there is enough slack cable so that the actuator arm will be at its fully open position. Adjust the calliper action on the disc so that it works correctly. Refit the cable and arm.
DO NOT operate the handbrake without the special tool ON or the cable fitted to the brake correctly. If you do the cable will get drawn into the unit and keep going until the motor jams. You will need to strip the unit as above to sort it out.
Another option is to open the cover of the EPB and unscrew some cable manually from the inside. Then you'll have to seal it using silicone gasket maker once again.
