sa utah Posted June 10, 2022 Report Share Posted June 10, 2022 after new discs etc on the rear of the car and adjusting the handbrake shoes as per the tech article I am perplexed as there is no way (it appears) to tack up the slack in the handbrake cable.... Expecting it to be a simple case of lifting up the access panel behind the brake lever like on the 986....... There are no adjustment screws/nuts etc. Can anyone tell me how to sort? I've done a little bit of googling and it seems the cable is "self adjusting". Maybe someone can tell me how that works as mine obviously hasn't ! Cheers.

That would appear to only leave the adjuster inside the hand brake brake drum. Quote Link to comment Share on other sites More sharing options...
sa utah Posted June 10, 2022 Author Report Share Posted June 10, 2022 Those adjusters simply move the pads relative to the drum. They don’t take up any slack in the cables. Quote Link to comment Share on other sites More sharing options...

iborguk Posted June 10, 2022 Report Share Posted June 10, 2022 (edited) Workshop manual link from my last post says the cable cannot be adjusted, self-adjusting, as you said. If you read that link on a Mac and stick it in reader view it's easier to read. Adjusting the parking-brake shoes This includes: Checking the free play of the handbrake lever and adjusting the parking-brake shoes. The parking-brake cable cannot be adjusted (automatic cable adjustment). Checking free play of parking-brake lever The parking-brake shoes must be adjusted if the parking-brake lever can be pulled up by more than 5 teeth or more than 10 teeth through application of medium force without producing a braking effect. 10 teeth applies to parking-brake levers with a modified/refined tooth system (introduction in standard production in February 2006). Information The first version of the parking-brake levers has a total of 12 teeth (index/last two digits of part number are less than 50). The modified version (refined tooth system as of February 2006) has 20 teeth. Adjusting the parking-brake shoes 1. Remove the rear wheels. 2. Undo the parking-brake lever and push back the disc brake pads of the rear axle until the brake disc can rotate freely. 3. The adjustment fixture can be twisted through the bores in the wheel mounting. 4. Turn the brake disc in such a way that the adjustment fixture becomes visible. Using a -screwdriver- inserted through the bore, move the adjustment device until the wheel can no longer be turned. To be specific, this means: put transmission in neutral. Further torque of the brake disc between 50 Nm and 150 Nm (37 ftlb. and 111 ftlb.) (test with torque click wrench on the drive shaft lock nut clockwise). Next, turn the adjustment fixture back again through 4 notches (release approx. 3 notches until the wheel can be turned freely, then release another 1 notch). Repeat the procedure on the other wheel. Adjusting the parking brake 5. Pull up the parking-brake lever (check free play). If 2 to 4 teeth or 4 to 8 teeth are engaged, it must be possible to turn both wheels by hand with considerable difficulty. 4 to 8 teeth applies to parking-brake levers with a modified/refined tooth system (introduction in standard production in February 2006). 6. Release the parking-brake lever and check whether both wheels can be turned freely. Edited June 10, 2022 by iborguk Quote Link to comment Share on other sites More sharing options...
sa utah Posted June 10, 2022 Author Report Share Posted June 10, 2022 Thanks for the link Great info and confirms the "self adjusting". i'll try pulling the lever repeatedly as that was the way to get the adjusters moving on my other car I seem to remember...... 1 Quote Link to comment Share on other sites More sharing options...

Yes, but if correctly adjusted it minimises the amount of cable travel before the shoes start to contact the drum thus shortening the cable travel required.
