jackb_ms Posted August 1, 2011 Share Posted August 1, 2011 Hi I was checking my rear brakes at the weekend. The driver side is not working, i.e I can turn the wheel by hand, the near side one is better but not 100%. There is plenty of meat left on the pad. The little lever which is connected to the cable moves when the handbrake leaver is used. Any ideas what might be causing the issue? Is there a guide on how to clean/ reapir the calipers?

Stationary M25 Traveller Posted August 1, 2011 Share Posted August 1, 2011 Assume you mean they don't work when the handbrake is applied ? How many clicks on the handbrake lever when you pull it up ? The cable can be adjusted (under the car if it is a central tunnel top handbrake). Maybe you need to remove the pads and screw the self-adjuster piston back in fully (with a proper tool for this), then refit the pads and press the brake pedal hard several times to actuate the self-adjuster (DON'T pull on the handbrake until after this self-adjusting).

jackb_ms Posted August 1, 2011 Author Share Posted August 1, 2011 Hi The test I made was with the handbarke on. *thumbup*Cheers for that I'll try it at the weekend Jack Link to comment Share on other sites More sharing options...
henry21p Posted August 4, 2011 Share Posted August 4, 2011 Handbrake tensioner. Handbrake off. Hand in near diff to the plastic nut. Adjust nut as tight as you can. Then, fingers clear, handbrake on as tight as possible. As you take handbrake off, pull cable backwards hard. Slack will appear between nut and bracket. Do up nut. Handbrake will become stiffer, pedal will become firmer and imbalance will be reduced. Link to comment Share on other sites More sharing options...
henry21p Posted August 5, 2011 Share Posted August 5, 2011 I take it that the brakes are well bled, there is no leak anywhere etc? Are you on flexible rear hoses? Link to comment Share on other sites More sharing options...
john milner Posted August 7, 2011 Share Posted August 7, 2011 Could the car be left parked up for lengthy periods with the handbrake on causing the pistons/pads to get corroded in the on position? Link to comment Share on other sites More sharing options...
jackb_ms Posted August 8, 2011 Author Share Posted August 8, 2011 Front brakes works very well. I never use the handbrakes, it is only tested at MOT. Maybe it is corroded in the OFF position! What are they from the rear calliper? Jack Link to comment Share on other sites More sharing options...
henry21p Posted August 8, 2011 Share Posted August 8, 2011 Jack - no it isn't - stop guessing and try adjusting it up. The handbrake pulls the cable, which pulls the arm, which activates the pistons. If the brakes work when the car is rolling - then the handbrake will work unless it is poorly adjusted. Link to comment Share on other sites More sharing options...
Billyboy Posted August 8, 2011 Share Posted August 8, 2011 OR One side of the cable has seized One side has a seized actuator arm one side has a seized piston one side has seized sliding mechanism (assuming single piston setup) as most 7ns have Does the foot brake work on the side the handbrake does not? Does the wheel spin relatively freely if jacked up and spun by hand - accounting for drag of transmission Link to comment Share on other sites More sharing options...
jackb_ms Posted August 8, 2011 Author Share Posted August 8, 2011 stop guessing and try adjusting it up I agree with that, it is difficult to find the hours to do it, with two young ones. Jack Link to comment Share on other sites More sharing options...
