'89 Gt Rear Brake Question/Help

daleclough · 07-22-2007, 05:31 PM

I have a "hum" from my passenger rear wheel when driving. When I apply the foot brake it goes away. The e-brake stuck once a few days ago but quickly released. The "hum" has been there since I bought the car 4 weeks ago.

Can soemone post a picture or diagram of what the brake set-up is supposed to look like? I may have to take the rear brake apart and have a look-see.

Any ideas on what may be the issue?

Thanks!

sounds like they are adjusted a little bit too tight.

could be chopped rear tire look for high or low spots on the inner or outer edge of the tires or possibly a bad wheel bearing if the noise gets louder when you load up one side of the car like when cornnering like if the noise got louder when making a hard left turn may be a bad right rear wheel bearing or vice versa......

woops didn't read the part about noise gooing away when applying brakes[:@] pull the wheels and inspect the brakes the drum may be warped or the shoes may be to tight or dragging

2 for too tight... cool.

So, what's the quick way to back them off? I can read the book but I'm sure someone has come up with a quick and better way to do this...

ON THE BOTTOM OF THE BACKING PLATE THERE should be a oval slot or a knock out....can't remember if you have to take a punch and knock open the oval,.....but if the oval is there if you don't have a brake adjusting spade/tool use a wide blade screwdriver and rotate the toothed wheel the way it is most difficult because you'll have to over come the adjuster lock it' takes a few trys but not all that bad
