The last few days the back brakes on my commodore have been making a noise. I poked my head under there, and low and behold, they pad was down to metal, and the disc chewed out. gay. So i bought another set of pads, and got a pair of discs i had lying around, and set out to change them. Pulling all of the pads out, i noticed that 3 of them are about 50%, and one was metal. After replacing them, i checked the same side, (passenger, outside), and noticed after a short drive the obvious burning friction material smell. The slides in the caliper were dry, so i greased them up a little, but this seem to have not affected the caliper/pad in any way. I figured that there may be heaps of **** in there, and it could be on its way to seize. Will a rebuild kit solve this? What other possibilities are there? Any of you experiences?

seized/dry slides will cause that, clean them out and relube them

That was what i thought when i had them apart, so i greased them up, but it didnt seem to help. I am going out to pull them apart again, and clean them up with some emery, grease them up, and clean the inside of the caliper too. See if that fixes it

i work for holden as apprentice i see this alot... normally the inside pad that wears out just clean ur cailper up n lube it...

Yeah, if it was the inside, that would make sense. But it is the outside. I pulled them apart before, and gave them a good clean, emery papered the bores, and regreased the slides. It hasn't made a difference. Now i am thinking the caliper may have warped. Will grab another one tomorrow off of another diff i have, and see if that fixes the problem. Can't hurt either way

I Have also discovered that the brake disc is rubbing on the outside of the brake caliper bracket. Could it have been the way they were assembled? Afaik, the spring washer goes on the same side as the bolt head, but moving it between the housing and the bracket gives adequate clearance. This also indicates that the axle may have moved approx 5 ml outward

sounds like deep sh!t... have u hit a gutter lately to put it all out mayb?

Check that the four nuts holding the axle retaining collar into the housing are still tight. Have you checked disc face runout? Your disc could always be warped. Axle bearing could also be shot, but that'd generally be quite noisy/vibrate.

It is always a good idea to machine the discs before replacing with a new pair of pads, this will avoid the discs to be warped, glace.

ive still got set of vn rear calipers if u want them u can come grab them off me aswell as the axles if u wantt ket me knoww k goodluckk
