    5.7 v8 rough idle, hesitation and shudders in reverse and drive only

    First off, I drive a 1998 GMC Suburban K1500 SLE with the 5.7 V8. Not too long ago I had the rear drums checked, front brakes replaced and a brake fluid flush. Since then, never before, for some reason I have the occasional shudder/hesitation while on the accelerator and a rough idle ONLY in...

    Rumor..

    My 1999 Tahoe has never had an awesome brake pedal with the engine running. When the trucks off and no vacuum supplied to the master, it feels like a firm pedal. I've heard a rumor that these trucks have a sensor that decides how much vacuum the booster gets and when it goes bad it overboosts...

    Dana 70 brake drum part number

    1989 k3500 srw dana 70. The drums from every part store ive tried are all way to tall from the hub mounting surface to the dust shield. I will try to attach a picture. All the other dimensions are on par with my old drums. Just the overall height is wrong. Has anyone run into this issue

    Issues After Hydroboost Swap

    So around 2 years ago I realized my parking brake wasn't holding my 98 K1500 in place when parked on a mild grade. She's an auto and I never use it but brakes is brakes and I don't skimp on safety. Ended up becoming a front to back brake job. Literally the only thing that didn't get replaced at...

    Brakes for towing

    I was driving the 92 k2500 doing a dump run going down hill with a load in the back of bed (no trailer) and the truck did not want to stop when I wanted it to. I plan on doing some towing with this truck (dump trailer and possibly short runs with a compact skid steer). So where should I start...

    Proportioning/combination valve re center

    After fitting new rear brake lines to my 92 K1500, the inevitable happened with the proportioning valve closing off the rear brakes and now being unable to bleed them. There are a few videos on the tube but I thought I would ask you guys as to your experience in re centering the valve so that I...

    Touchy Brakes

    I've got a 99 Tahoe LT 4wd 4dr with 4 wheel antilock brakes (currently not working). When I press the brake pedal, nothing happens until the very end when the brakes grab violently. At low speeds my passenger rear wheel locks up. I went on Identifix and they say it's either a BPMV (Brake...

    Brake Upgrades

    I just bought my first truck, 1998 GMC c1500. Brake pedal is really soft after changing fluid and replacing front pads and rebuilding the rear drums. Anybody know of kits that give it a little more stopping power that aren't crazy expensive?

    K-H ABS Delete? Replacing Brake Line Questions

    Brake system is a JB7. Truck is 2000 K2500. So after doing some poking around I've seen a lot of info for pre-94 trucks removing ABS since they have a different system. On the trucks with the K-H ABS module, if I remove the ABS system is there anyway to do it where the light won't come on? Also...

    Brake system help!

    ok. So I was getting tired of the spongy pedal on my 88 C1500. Decided to do the RWAL delete and new stainless hoses. After bleeding the brakes the pedal was even softer than before. So I went and got a NBS master cylinder. Bleed the brakes again and it just as bad if not worse. I can’t figure...
