3800 Rear Brakes 101

[LeeGTP]

I need to change my rear pads and rotors soon. No pad left on the drivers side and rear rotor is grinding. Is there anything special that I need to know? before trying to change it on my own. Like torque on the bolts or do I have to bleed the system etc etc. Thanks

i could look up the torque specs for you if you need...
going by what you say in above... that is not very good. you should have even wear on all your pads. fronts wear faster than rears but you should not have unusual wear from side to side. this tells me that there is air in the lines, a line is clogged up or you have a hose that is going bad and ballooning.
I would DEFINATELY bleed the brakes after you change the pads. as a matter of fact, if I were you, I would do a whole fluid flush.

other than that, brakes are pretty straight forward.

Lee-

The process is pretty easy, you will be suprised!

1. After you remove the wheel the first thing to come off will be the caliper.
2. There are two bolts on the back side of the caliper.
3. Once the caliper is off you can pull off both brake pads.
4. Once the brake pads are removed, you can now un-bolt the brake pad bracket.
5. There are also two bolts on the backside that remove this.
6. Once that is removed the rotor should come off with ease.

You should not have to bleed any brake lines as long as you keep the brake line attached to the caliper. Hopefully I haven't missed anything

Here are some torque specs for the bracket and caliper.

For the Rear Only:
Bracket Bolts: 92 ft. lbs.
Caliper Bolts: 32 ft. lbs.

Here are the Fronts in case you need to do those soon...
Bracket Bolts: 137 ft. lbs.
Caliper Bolts: 63 ft. lbs.

Good luck

dude, just take off the 2 screws for the caliper and the caliper braket. take the pads off and the rotor off. get some disc brake quiet and spray it on the back of the pads and then just put back together. dont worry about torqueing anything cuz its gonna be harder than what it has to be to get a torque wrench in there. just tighten up the bolts and call it a day.

Alright cool seems preety simple
Thanks again

you also need to compress the caliper piston to allow fo the new pads to slip over the rotor when reinstalling.

First you unscrew the cap on the brake fluid reservoir under the hood. then what I do is use the old pad thats on the back of the caliper and a C clamp and just tighten it up untill the piston is fully compressed. then take the old pad off and replace with the new pads.

D@MN I got to get a C clamp too.
alright thanks
I really appreciate the help. ILGPC Rocks....

i just finally did mine, and had no clue. I took em off, there were 4 bolts on each side, replaced stuff the exact same way, and I still haven't wrecked.


and the whole shaking is gone. lol

did mine yesterday...14 MM bolt.. first timer here! :lol:

ive got a c-cramp if you need it. B)

 

[mybluegtp]

If I can do them then you should all be able too.. :lol:

Thanks all who gave me their advice I finally did them it was preety easy and straight forward so far so good. C-Clamp good thing to use when compressing. I can't believe what they charge at the delearship and brake places to do them. I'll do my own or now on.
