moose Posted December 19, 2006 Share Posted December 19, 2006 I question iam asking for a mate who is trying to sort the brakes on his 1977 series3 88" Hes got a brake overhaul kit eg all the internal bits needed. But he is having trouble getting the drum off the hub hes undone the 3 screws on the drum face and slackened off the adjustment but the drums will still not come off any body else had this problem? thanks for any input Quote Link to comment Share on other sites More sharing options...
rtbarton Posted December 19, 2006 Share Posted December 19, 2006 Will they move at all or are they completely stuck. There should be a fourth hole in the drum which is threaded, use a screw to jack the drum off the hub. It will come off at an angle, so gently tap the edge opposite the screw to straighten it up as it comes off. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted December 19, 2006 Share Posted December 19, 2006 On the face of the drum there is a threaded hole, it's the same thread as a V8 head bolt (7/16" UNC according to the manual). Wind one into the hole and the drum should come off. Tapping round the drum edge in circles helps too. Beaten to it by Roger! Quote Link to comment Share on other sites More sharing options...
Ivan Posted December 19, 2006 Share Posted December 19, 2006 I have also found that gently tapping around the drum whilst pulling the drum sometimes frees them off. HTH Ivan Quote Link to comment Share on other sites More sharing options...

Tonk Posted December 19, 2006 Share Posted December 19, 2006 11" front drums have 2 adjusters, make sure he's backed them both off then give em a clout Quote Link to comment Share on other sites More sharing options...
simonb Posted December 19, 2006 Share Posted December 19, 2006 The thread of the 4th hole should be the same as the thread of the 3 screws that hold the drum on. Apply some grease to the threads of the screw before you put it in. Gently tap the opposite side of the drum with a hide hammer or normal hammer and block of wood for each half turn of the screw. If the drums are badly scored with a wear ridge, you may have to lever off the drum with a tyre iron or broad screwdriver. You may wreck the drums (and shoes) but if they are that worn they should be replaced anyway. They are cheap anyway only about £10-15 each.

moose Posted December 19, 2006 Author Share Posted December 19, 2006 thanks all, going round to look at it now... now even more fun as its only 2degC outside Quote Link to comment Share on other sites More sharing options...
Phil Hancock Posted December 19, 2006 Share Posted December 19, 2006 any idea on the size of bolt i would need to use in that four hole ? Its 3/8" BSW by rights but a UNC bolt would do if you cant get a BSW bolt. Quote Link to comment Share on other sites More sharing options...
