Rear brake help

9838stang · May 31, 2013

The other day i looked at the rear brakes and they looked pretty back on the drivers side. So i went to oreillys got some rotors and pads. I painted the rotors so they didnt look like crap after the 1st rain storm. Well after spending 3 hours looking for my lugnut key and the rear caliper tool, i got the rotors off and touch up the calipers and the brackets. got it all back together that night. went for a spin to see how it goes. I get 15 blocks from home, and come to a stop at a light and i see smoke passing me. Im like fawk now what. I pull over and start looking and the passenger rear wheel well is pouring smoke out. I get pissed and im thinking well maybe it is just the paint burning off. Now i taped off the contact area so i didnt get paint on the pads. Well i pull the hand brake a few times to see if that would free it up. i drive another 8 blocks and come to a stop only to have more smoke than before coming out. I run home and tear into it. jack the car up both wheels seem to move ok a little bit of work to move them, but they spin. So pull the caliper off look at it to see what is happening. Well in that short time span the pads got cooked. literally a mile maybe 2 and the pads got cooked and i never got able 30 mph.

Well i rotated the piston back in again, and bolt everything back up. Pass side is free now, and the driver side now has that crap load of resistant on it.

Took it for a spin around the 5 blocks to stay closer. Come to find out now the driver side is now getting hot. I pulled the wheel off and pull the caliper off and play with the hand brake lever on the caliper and the piston didnt move. Im hoping its the driver side caliper but i might as well replace both rear calipers.

Any ideas as to what it could be. 1998 v6 auto no abs,

If it's hanging up that bad I would have to guess it's the caliper gone bad my dude. Are your rears cobra brakes too? Not sure how hard cobra calipers are to come by.... I had a similar issue with mine except it was the ebrake cable got seized up and caused my wheels to damn near catch fire lol. It's been disconnected ever since on the driver side

the calipers are the same regardless of v6, gt or cobra. the brackets, pads rotors are different for the cobra, that's it. i'd recommend getting some reman'ed ones. i priced them out and it was like $160 for both sides.

I didnt change to the cobra rears since im not willing to pull the axles out just to put on a 1 in larger rear rotor. But the issue was my driver side caliper was seized up. replaced it and problem fixed. got a reman on for 60 bucks after a core.

Did you pay attention to the two "V" shaped cut-outs on the rear piston and their position before you reassembled the brakes? If not, that's your problem. Those two tits on the pads need to be in those "V" grooves on the piston.

Here's a video from Full Tilt Boogie Racing that explains it all:

Hope that helps.

Thanks for the help bud but yep I know the the raised part on the pad needs to sit in the v dimples on the caliper piston.0

Did you grease your slider pins??

Yep everything everything was moving free other than the driver side caliper. Now the new driver caliper and everything else is working great thanks the the help
