Mattyc Posted May 9, 2020 Share Posted May 9, 2020 Morning All First post so hello all and thanks for letting me join. I'm sure there has been loads of defender rear drum brake questions, but this is a weird one All new parts fitted to rear brakes as old ones shot. Everything seems to be fitted ok and adjusted correctly, but on a road test the rear shoes are locking on completly and don't seem to be pulling back???? A new master cylinder and servo has also been fitted, could this be causing the problem? Has anyone experienced this or throw any light in things?

Anderzander Posted May 9, 2020 Share Posted May 9, 2020 Hello ! Have you fitted the trailing and leading shoes in the right place ? Quote Link to comment Share on other sites More sharing options...

Mattyc Posted May 9, 2020 Author Share Posted May 9, 2020 Hi All Checked everything out today and springs and shoes are as per the attached photo, which as far as I know is correct? Did a check with the drum off and the piston is staying pressurised after the brake pedal is released, could a faulty g valve be causing this?

Anderzander Posted May 9, 2020 Share Posted May 9, 2020 The link from Sigi is good.... Have you a photo of your set up ? Quote Link to comment Share on other sites More sharing options...
Sigi_H Posted May 10, 2020 Share Posted May 10, 2020 (edited) I switched to a Salisbury with disk brakes. Does not brake harder, but is a lot easier to maintain. No adjusting by hand each half year. I have a '83 Oneten and my setup was identical to the pic in the link. Edited May 10, 2020 by Sigi_H Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted May 10, 2020 Share Posted May 10, 2020 Is there a bit if free play between the servo and master? If not the servo wont release the vacuum and release the brakes. Quote Link to comment Share on other sites More sharing options...
chuff Posted May 10, 2020 Share Posted May 10, 2020 Hi Matt, Quality Slave cylinders are no longer available through the normal stockists, I can only assume that you have chinese or Italian copies of girling cylinders. If so then it's very likely that the spring inside the cylinder is FAR FAR too strong, this stops the pistons retracting properly. Put the original springs in the new cylinders, if you still have them. Keep EVERYTHING that says girling, you can have it rebuilt by Contract Auto Engineering in stourport. Also check that the trailing shoe has the retainer bolted to it correctly, the two retaining screws should be on the Rear shoe. Regards, Adam.
