Rob Posted October 30, 2011 Share Posted October 30, 2011 Having got my car back on the road after an 18month lay up, I've now found the OS rear hub drum is heating up a bit, enough to flake off the fresh undercoat and hammerite I put on to stop it looking all horrible and rusty. I spent this afternoon re-adjusting the handbrake, both with clicker barrell adjuster (8 clicks back-off) and then adjusting the cable at the lever in the drivers seat, and repainting it (the drum). The car rolled easily on the drive, so I didn't think it could still be binding, but having driven to the shop and back there is still heat in the disc/drum. The NS one was cold to the touch, the OS caliper was also cold to the touch, so it must be the drum brake thats heating. What can I have done wrong? When it was up on stands I found it hard to turn the disc forwards but easy backwards, would this be the diff as opposed to anything in the handbrake?

BK1 Posted October 31, 2011 Share Posted October 31, 2011 Hope you get an answer to this one mate as I've got the same problem. I'm wondering if it's the cable binding somewhere and not allowing the springs to return the shoes when you release the handbrake. I've done all the adjustments I can. With the disc off mine looks like the leading shoe sits further out than the other. I'm gonna have another look Tueday after work. If not I might give Chris Wilson a call. I met him last week, he'd serviced my front calipers, what an excellent bloke. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 31, 2011 Share Posted October 31, 2011 BK1 and Rob: Be sure the shoe linings are not coming un-bonded, if they get loose the handbrake shoes are self energising, once they start rubbing they tend to pull themselves on tighter. The shoe friction material may even break loose and try and lock the drum up, older Volvos do this and it's err, a bit frightening Be sure the cable is totally free and not sticking internally, disconnect both ends and see if pushes and pulls with no real drag.

Dnk Posted October 31, 2011 Share Posted October 31, 2011 Strip down, clean and rebuild with new shoes, check cable moves freely. I've just done mine and fitted new discs as the internal drums where the handbrake shoes operate was quite badly corroded Quote Link to comment Share on other sites More sharing options...
Rob Posted October 31, 2011 Author Share Posted October 31, 2011 It had new shoes a couple of years ago. As I said, it'll roll on the drive with little effort as there is the faintest of inclines, which makes me think the pads can't be binding unless this is a red herring.

Chris Wilson Posted October 31, 2011 Share Posted October 31, 2011 You could try it with no handbrake shoes in the side which is heating up, then you'd know for sure if it's shoes or pads. Don't try it with no pads in though.... Quote Link to comment Share on other sites More sharing options...
Rob Posted October 31, 2011 Author Share Posted October 31, 2011 Its definitely not the pads, as the caliper was stone cold. I'm jsut wondering if the shoes can be clear on the drive, but somehow start to drag when driving. Could it worth another 2 clicks off the adjuster?

Chris Wilson Posted October 31, 2011 Share Posted October 31, 2011 Try taking 12 or 15 off and see if it fixes it, I suspect the cable from what you say. Once set don't use the handbrake at all, test, if it stays cool, apply handbrake very hard, release and test again. Quote Link to comment Share on other sites More sharing options...
Rob Posted October 31, 2011 Author Share Posted October 31, 2011 Will do, bearing in mind the NS will pull more during hard handbraking. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 31, 2011 Share Posted October 31, 2011 I meant apply it whilst stationary Quote Link to comment Share on other sites More sharing options...

Scott Posted November 1, 2011 Share Posted November 1, 2011 Wouldn't be the bearing would it? Is it definitely the shoes that's making it hard to turn? Quote Link to comment Share on other sites More sharing options...

Rob Posted November 6, 2011 Author Share Posted November 6, 2011 Hmm, well had it all in pieces today, and everything was free moving. Reassembled and it was cold after a short run, so maybe whatever was sticking got moved about a bit. However, should the whole handbrake shoe assembly be movable by hand. It all pivots about the top cam thing, that the shoe springs clip onto, but I can move the whole lot from side to side from the bottom. Is this correct and normal?

Chris Wilson Posted November 7, 2011 Share Posted November 7, 2011 That is correct, as I said, it's a self energising (self servo effect) movement, and that's how the work. So no problems there. Quote Link to comment Share on other sites More sharing options...
Rob Posted November 7, 2011 Author Share Posted November 7, 2011 A short 1 mile drive left it cold, so whatever it was, has gone during the disassembly / poking about / reassembly process. I hate it when that happens. Quote Link to comment Share on other sites More sharing options...
