2003 silverado 14 bolt drum to disc conversion help


AC SS

Recommended Posts

So I got a 14 bolt rear end off 06 silverado ss and had it narrowed 3 inches on each side and added the disc brake backing plates while it was getting narrowed . I got it back and I had an ssbc brake kit for a 06 tahoe included calipers and rotors I bought tahoe caliper brackets and put everything toghether. Now the problem I'm having is the rear driver side caliper seems to be sticking I put truck in reverse and it won't move until I press gas it seems to move foward better but not as smooth as it should..what can be wrong ? I've taken it apart 10 times thinking I missed something but nothing seems wrong I've greased pins and shims ? Any suggestions ? And I drove truck up the street and back home and notice rear driver side rotor extremely hot compare to passenger rear brake

It's either a hydraulic issue or clearance issue. I assume you haven't noticed anything rubbing or heard any noises? So, with the rear tires off the ground can you spin the wheels by hand? If it feels free until you press the brakes but then it feels stuck , I'd think it's a hydraulic issue ....like the hose or caliper sticking. If this is the case you can open the bleader screw, if it realeses the pressure right away and you are able to spin freely by hand you'd have a bad hose. If it's still stuck with the bleeder open it would be the caliper sticking.

 

If it's stuck has soon has you bolt the caliper on without even pressing the brakes then I'd guess it's a clearance issue. Like pads too tight in the bracket or too thick.

 

If it's free until you put bolt the wheel on id think the rotor is hitting the backing plate or bracket.... But in that case you'd probably hear the noise or see the grinding marks.

Oh also , I think there is a inner and outer pad on those . They look pretty much the same except the nubs out the outside of the backing . If you got them mixed up , the ears on the caliper could be hitting the nubs on the pads and not fully seating flat against the caliper ear. This would cause it to be too tight But usually you would have a hard time sliding the caliper over the pads to get it bolted in. It's still possible to bolt it on though. Since the rotor doesn't sit true until you bolt the wheel on you might not noticed the tightness until the wheel is on. You could also just thread some lugnuts on without the wheel , just to check if that's the point that it starts getting tight/ sticky

Thanks for the help ..no rubbing anywhere other than the pads seem to be to tight even with out pressing brakes passenger spins more freely than driver side ...what would be a solution for this ?

Did you have to force the pads into the bracket.... Like with a hammer? It should be snug but not tight... They need to move back/forth. If the pads are too tight in the bracket I usually grind/sand/trim them down a little on the ends and the sides on the edges of the ends. Don't take too much off because you don't want want them ratting up/down. I also dab a little brake grease on the ends .

Pads fit on bracket smooth...but once I put the caliper on its seems the pads are very tight against the rotor ....also just took it apart now and pressed on brake to see what caliper is doing and notice 1 of 3 pistons is moving and other 2 are not is that normal ?
