    Angry Need Help with Brakes!

    I have a 1998 C1500 and I recently bought brake pads to replace the old ones, and the new ones seem to be too thick, because even with the caliper piston compressed (completely flush with the caliper) the pads wont fit, even with one pad (the outer most pad) the caliper would NOT fit on the rotor. Does anyone have any ideas?

    You could always try grinding them down to get it to the right size and get them to fit.

    Do your old pads have the relief notch in the back side? If so do the new pads also have this notch? If not take them back & get the right ones. If notched you must slide the tang side pad first, & slide it into the notch. That will give you more room to slide the remaining pad into the other side.
    If your old pads did not have this style then disregard.

    Sounds like you have the WRONG pads. If you can, take one of the old ones with or I would recommend these pads Hawk LTS (Light truck SUV) pads. Part # HB332Y.654 $ 74.04 + shipping.

    See, thats the problem, Because I went back up there a few days ago and said that these must be the wrong brake pads and I was assured that they were not the wrong ones, I even saw the monitor and these pads fit 97-00, and everytime I go in there now and complain that they dont fit, I get looks like I dont know what im doing, because this is NOT the first time I have ever done brakes BUT this IS the first time Ive ever had this problem!

    Arbitert, look at the backs of all of your old pads. Do you see a relief notch in 2 of them, or in all 4 ??

    Is it possible that someone along the way, replaced the calipers with something not specific to the 98 C-1500 ? I happen to be in the automotive brake business, and I've NEVER come across a pad for any chevrolet's with a 'relief' notch in the backing plates. I'm not saying, it's not possible! It just doesn't make sense. Based on what your describing. The pads, being too thick even with the piston fully collapsed back into the piston bore of the caliper. This indicates to me, that you need to take the VIN number off of the vehicle, or insurace card, call a GM dealer, get the GM part number, and cross reference it, with the pad supplier of choice. I gave you the part number and cost of a Hawk brand pad and model that I HIGHLY recommend.

    Call me if you have any additional questions, and I'll see what we can come up with.

    Hope this helps,

    Keith

    Default pads won't fit

    Is this a rear application, aluminum single bore caliper? If that's it, then I'd suggest checking if the inner and outer pads are switched. they have nibs that will make the caliper not fit on the rotor if switched.

    I'm a QE at the plant that makes the oe calipers for the Silverado. If you can, take a pic and I can easily tell you if they're the right pads.
