The Big Bad Brake Thread

My Rear Right brake pads seems to have worn unevenly. I'm wondering if it's because of the pin not moving smoothly. On the front pads the pin/bolt seems to be the same thing and I lubed that up before reinstalling. But the rear pin and bolt are two different parts it seems. What is a good way to take off the rear pin and lube it so that I make sure the new pads wear evenly. I don't want to need new pads again. Thanks!!

edit: I think i found how to remove the rear pin based on some youtube videos of similar style pins from other vehicle makes. I'll update when I've finished the job tomorrow.

So the Cadillac ATS comes with brembos and from what I can tell the standard wheels are 17"s. There isn't much information out on them yet but from what I could find the ATS has a 12.7" front rotor. What I was thinking was GXP rotors and ATS 4 piston brembos. So I decided to try to bolt the ATS calipers on my car to see if they cleared my 17" bullitt wheels. The calipers bolt on 100% no problem, the wheels do not clear lol.

It is hitting the inside for the rim as far as the diameter . or against the spoke of the rim? Would wheel spacers help?
 
Yes wheel spacers will help if it's hitting the inside of the rim (hub) now if it's not clearing the rims itself a spacers not going to fix that
 
I am currently trying to do this to my 2001 Grand Prix GTP right now. I have all the parts I need. I got my calipers off a 2000 Camaro and I think the rotors are from a Caddy. I would have taken the calipers off the Caddy but where the brake lines mounted I kind of thought better safe than sorry and took Camaro ones. My only concern is using the brake lines on the car right now and if there is enough clearance. Can I use Camaro brake hoses? I am just trying to get the car back on the road after I changed out the motor.

follow this how too. http://www.regalgs.org/topic/54303-f-body-brake-upgrade/ its a regal web sight but its from a GP forum and the car is a GP too. not that it matters tho.
 


The other question is, does it take the GXP Rotors?

ATS:

GXP:

I hate converting...
Dia.: 323mm
Height: 52.32mm
Thickness: 32mm
Min Thickness: 29.9mm

So 1mm increase around the edge, which doesn't sound like a alot but this could be just enough to not clear

The ATS rotor being taller is a good thing, which usually means the caliper sits in further, so a washer or two like the CTS-V calipers to center it; which is much easier than trying to take away and grind something.

Pretty much all GM vehicles have the same spacing between caliper bracket bolt holes since 2002. Guess it was easier for them, so they could stamp out things without too much recalibration for different vehicles.
 
There is usually more than a few MM of wiggle room inside the caliper, I really think this is a viable idea for people wanting brembos without custom wheels but I'm not putting 18's on mine just to clear the brakes. I like my fbody setup and already have a tough enough time finding slicks that fit. Just thought I would post it up for info for anyone more adventurous than me.
 
I haven't read the whole thread, but in the few pages I did read, I haven't seen the 2000-2005 impala 12" upgrade mentioned? How would that compare to the two piston F-body calipers?

almost the same thing, the impala calipers are also dual piston, the disk is a bit smaller iirc.

F bodys would be easier to find if your junk yard hunting.
 


After reading that thread, it appears 2006+ calipers are dual piston, not 2000-2005 impala calipers, which appear to be the same as stock GP calipers. The "12 inch Impala upgrade" consists of the 00-05 caliper bracket, pads and rotors... No need to bleed the system after doing that.

That means the 2006+ impala calipers should bolt right up to a GP, right? Seems like that would be a bit more simple than the f-body upgrade, yet yielding the same stopping power.
 
its the dual piston that makes the difference if you ask me. single is weak.

i got the F bodys, its like night and day over stock. they feel very much like stock for normal driving, but once you need to stop fast, you got brakes and some.
 
Scotty how difficult was the upgrade? I have the calipers but what else do I need? The lines correct?

its as easy as changing your calipers and rotors. you just need to get the steel sleeves to keep the bracket bolts centered in the knuckle.

SS lines are nice, but you could use the factory rubber F body im sure. the SS line wont swell or burst and help firm the pedal some.

if your missing the caliper brackets, you'll need them.
 
Welp I'm off to find lines lol. Thanks.

Also. Confused about the steel sleeves lol.
