wimpus Posted October 15, 2021 Report Share Posted October 15, 2021 Hi all, Since as long as I can remember have a knock sometimes when I brake. Now its nearly everytime. Begin september changed the drums and shoes (cant remember if I had it before or not.. ). Shoes are adjusted the right way, springs and shoes also the right way in. Wheel cilinders is a few years old. What could it be ? 🤔 Not tried it yet with the handbrake cable removed. Yesterday evening noticed when I got the handbrake on and drive off. A knock when applying the brakes the first time, after that all good. Or if you stop, drive backwords, then forwards and again like above, first brake after driving forward.. knock.

Shafts where also renewed in 2018 (I think it was) with fully rebuild assembly's from TD Fitchet. Also checked the trunnion bushes, seems no play now (1 had a bit of play as bolt not very tight ).

Pete Lewis Posted October 15, 2021 Report Share Posted October 15, 2021 sounds like the HB cable is holding the shoes open dont let the axlles hang, disconnect the HB cable firmly lock up the adjusters set the cable to a nice fit , no tension and then de adjust to free the drum wear in the back plate hb pivot point can restrict the cyl from sliding but this just sounds like shoe shift knock Pete 1 Link to comment Share on other sites More sharing options...

But did grease up the habdbrake lever + wheel cilinders so it all slided good. Will check the cable, did got it a bit more loose yesterday + greased up the handbrake cable guides. Maybe best to degrease them all good and apply some grease. Link to comment Share on other sites More sharing options...
NonMember Posted October 15, 2021 Report Share Posted October 15, 2021 Lots of good advice above. Just to add, a knock like that can, sometimes, happen if the rear spring bushes are worn, although that tends to also happen on pull-away. 1 Link to comment Share on other sites More sharing options...

New spring was fitted at the end of july as my previous one said 'bang' (bottom leaf broke). Link to comment Share on other sites More sharing options...
wimpus Posted October 16, 2021 Author Report Share Posted October 16, 2021 This morning took a look. Right side all ok. Left side found out the wheel cilinder moved more.. One of those 2 sliding/hold down plates had gone missing, so thats why the cilinder moved and made de 'knock'. Lucky I never trow away old fitting kits etc (keeping it all in sorting boxes), so only took 5min to fix. Also cleaned up the handbrake cable of old grease and dirt, now slides a lot better. Thanks all of you for helping Link to comment Share on other sites More sharing options...
