Jamesc183 Posted February 20, 2013 Share Posted February 20, 2013 Hi guys, im having trouble adjusting the drum that loosens the rear driverside disc! Im trying to move it with a flat headed screw driver but it just wont budge at all! I understand theres another way by fastening in two screws to push the disc off? Does anyone by any chance know the exact size of the screw so i can buy them! Thanks JC Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted February 20, 2013 Share Posted February 20, 2013 I just bashed mine off with a hammer, really bashed. It should fly off and then you will see the hand brake... Quote Link to comment Share on other sites More sharing options...
Jamesc183 Posted February 20, 2013 Author Share Posted February 20, 2013 Ill have to try that! Sounds vicious! lol Does anyone know why the adjuster wont move? Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted February 20, 2013 Share Posted February 20, 2013 If it won't move either way then it's probably seized. I can't remember the set-up in the Supra to be honest as I've only had the rear disks off once but going on the usual arrangement of a shoe type brake the adjuster will only turn in one direction, if working properly, unless the racheting arm is held away from the toothed wheel on the adjuster. The arm keeps the adjuster at the correct tension to ensure the brake is effective. Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted February 20, 2013 Share Posted February 20, 2013 please forgive me for asking but you don't have the park brake pulled do you? Quote Link to comment Share on other sites More sharing options...
Jamesc183 Posted February 20, 2013 Author Share Posted February 20, 2013 please forgive me for asking but you don't have the park brake pulled do you? Ahaha Hell no! Well thats a pain looks like i might have to replace the handbrake shoes too then! Anyone know what size bolts i use to push the disc off??

Benjy Posted February 20, 2013 Share Posted February 20, 2013 I think they're M8 or M10 x 1.25. You should be able to turn the adjuster to slacken them off. If you can't, I'd order an entire brake shoe kit, springs, adjusters the lot. Quote Link to comment Share on other sites More sharing options...
Jamesc183 Posted February 20, 2013 Author Share Posted February 20, 2013 (edited) Damn ive got a feeling its seized or something? Edited February 20, 2013 by Jamesc183 (see edit history) Quote Link to comment Share on other sites More sharing options...

Dnk Posted February 20, 2013 Share Posted February 20, 2013 Page BR-60 has a good diagram of the handbrake You really shouldn't have to smash the disc off though, i'd try spraying some penetrating fluid through the hole onto the adjuster You can also tap round the outside of the drum with a copper hammer which can help to free off the shoes. Last resort is to bash them off and as said if you have to do this get a new fitting kit (Toyota)BR.pdf Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted February 20, 2013 Share Posted February 20, 2013 Does the disk spin freely? If so then the disk might be just tight on the hub itself. Quote Link to comment Share on other sites More sharing options...

Last resort is to bash them off and as said if you have to do this get a new fitting kit (Toyota) I see from that diagram now that the brake shoe adjuster doesn't have that one-way rachet arm I mentioned earlier so in theory the adjuster should turn either way when levered with a screwdriver. The jacking screws are probably 8 x 1.25 mm but be careful not to apply too much pressure as you can burst the disk. Be sure that the bit of the hub that protrudes throught the centre of the disk is rust free and spray some penetrating fluid between them before attempting to jack off. Sorry, couldn't help myself.

Jamesc183 Posted February 20, 2013 Author Share Posted February 20, 2013 Thanks for the response's guys! Gonna have a crack at this at the weekend! Thanks I will spray fluid before jacking off! Quote Link to comment Share on other sites More sharing options...
Jamesc183 Posted February 20, 2013 Author Share Posted February 20, 2013 Guys i just realised that the hub was actually spinning with the hand brake off but the adjuster just wouldnt move! Does this still mean that the handbrake shoes have seized? Because I would of thought the whole thing would be stuck (as if the handbrake was on) if it was seized?

pedrosixfour Posted February 20, 2013 Share Posted February 20, 2013 Well if the disk is spinning freely then your handbrake is not, or at least does not appear to be, the issue. Quote Link to comment Share on other sites More sharing options...

Dnk Posted February 20, 2013 Share Posted February 20, 2013 Try going round the outer drum diameter tapping it firmly with a copper hammer and also tap on the face where the wheel studs are then use the extraction bolts to try to ease it off.

Scooter Posted February 20, 2013 Share Posted February 20, 2013 I did mine at the weekend and the disks were stuck firmly on the hubs and I had no threaded holes. So I sprayed penetrating fluid in any hole I could find on the disk face and I tapped firmly the disk from behind ie hammer in the wheel arch, where there is no dust shield, rotated it a bit a tapped again etc etc until it popped off.
