help with VH's/brakes

[900]

ok, don't throw up just yet...
i have a problem with my rear right drum brake - besides the obvious problem of it being a drum brake, it makes a grinding noise when it rolls and when the car is very slow (like when applying the brake) the car shuds forward with the wheel, suggesting to me that it's "buckled" or the studs are bent.

this all came about today after trying to put walkinshaw rims on the rear. the inside of them must have locked in with the drum cause the car wouldn't move in reverse or D after a metre each way (foot off the brake+no accelerator). the car now has the stockies on the back.

any advice before i take the car somewhere would be sweet.... or any linkage to other forums that might be able to help. ta.

Have you ripped the drum off to have a looksee?

Could be no pad left on the shoes...

Dunno why different rims would make a difference though??

i figured that at first but walky rims definately should suit disc brakes only. fuckin' pity.

i've just pulled it apart now. it seems fine but i'm not upto to speed with drums so it may be staring me in the face.

with the drum off+drive in neutral, i can rotate the studs and it makes no grinds or locks up but once i put the drum back on, it has a small section of say, half a rotation, where it grinds and slows up.

put a plain stockie on, tighten it right up, (have now tried both right side wheels) and it has a huge grind and fully locks up after less than half a rotation. of course, if i loosen the wheel it goes back to a slight grind and slightly tougher, less than perfect rotation.

fuckin' drums... seriously.

Ive had this problem before, how a specific wheel would pull the drum in further. And push the shoes onto the backing plate.

With the bucked problem, do you know how to de-adjust the shoes? De-adjust them all the way so they dont contact the outside of the drum, and give it a go. If youve solved your siezing problem then go to this next step.

How did you get the drum off? smacking it on the face or smashing it on the side, side will buckle it bad and you will get exactly this problem.

Have you just put new drums on? Ive also had this problem after using chinese drums. (you cant get anything well made anymore)

If the answer to these questions are resulting in it being bucked or warped or whatever. Measure the id and see if its too big to machine. If it is chase new drums and standard size shoes

I just pulled them out. i pulled the left drum off just then and it has a similar problem but it's very, very small and you probably wouldn't notice it whilst driving.

Have you just put new drums on? Ive also had this problem after using chinese drums. (you cant get anything well made anymore) Nah, i'm pretty sure they're original

i've had enough of fiddling with it now; there isn't much more i can do at the moment (being a sunday and all). i think i just need new shoes for it? - the drum seems fine.

[joshg123]

shoes wont do that, drums will be out of round cos of hot spots or human interferance

[900]

ok, then how do i de-adjust them? by that, do you mean... bringing them inwards? so they only touch the outside when handbrake is applied?

[RICEY]

Should be an adjuster between the pads, looks like a metal tube screwed into another metal tube with a sprocket looking bit on it. You wind it in and out for adjustment using a screwdriver on the sproket and levering it around. Work out which way is winding in then wind in a few clicks and replace the drum. Keep doing this till the resistance goes away. It works like a ratchet so to wind it in you may need to lever the metal plate off that sits on the sprocket to allow it to turn that way.

Only prob is this may render your handbrake useless.

Im presuming all drum brakes are the same so I may be wrong here hahaha.

Or have some one who knows what there doing look at it ..

Odin auto spares in balcatta is open on sundays. Someone there should know about the problem and be able to point u in the right direction. Great place imo
