Hi, you didn't say when this happens. All the time ?, just when slowing to stop, etc. Did you bleed all 4 wheels ? Here is a quick run down of brake problems with these trucks. My experience would say, if all the time, its master cylinder or a blown out brake line leaking fluid. When slowing to stop sign, ABS could be acting up. Pedal feels good until you just about stop, then you will feel a vibration from ABS activating. When the ABS acts up, it will also give the same symptoms as a bad master cylinder. This can be proved by pulling the ABS fuse. I''ve been driving with the ABS fuse out for 3 yrs. This was a recall, but GM never actually fixed the problem.
I'm not a mechanic by trade, just posting how I solved my problems. More importantly, look at your brake lines on the frame, they will rust out with no warning !! I've replaced everything, pads, rotors, hubs/bearings,etc, It was;t until the brake lines rusted out and replaced, that the brakes felt better since new.
 
How about some more details. These truck have numerous brake problems. ABS senors fail, brake lines rusting, front hubs/bearings, all brake related.

Hello, new to site and hoping for help !
I'm pretty much a DIY guy but I'm currently baffled by something that's never troubled me before, installing brakes. I recently purchased a 95 stepside (excellent shape) from someone who mostly garaged the truck. At the purchase I was informed that there was a "pulling to the left" when ever you stepped on the brakes. I instantly thought..air in the brake lines, piece of cake. The previous owner stated he tried fixing with no luck by replacing the Master Cylinder and new steel brake lines. Since, I've installed new front pads and calipers and rear shoes with new wheel cylinders to both sides. I also bled the system with new fluids, have no air in lines and I have full/hard petal. The ABS dummy light also remains on as like the day I bought it from the previous owner. Basically it's a complete new system from master cylinder, steel lines to brakes and wheel cylinders and I'm still getting a hard pulling to the left when you mash the brakes. Sometimes it almost jerks the steering wheel from your hands if you really get into the brakes (sudden stopping). I have no sounds coming from the brakes, overall it's a quite ride and there's no play or slop in the steering. I've also replaced all tie rods with alignment. Drives straight as an arrow except the moment you mash the brake pedal.
I haven't replaced the front disc cause the old pads had even wear so I didn't think they were warped. Nor did I replace the flex hydraulic lines on either side since I was getting good brake fluid flow as I was bleeding the brakes along with the pads grabbing the disc.
Could it be any of the ABS Control Module, the ABS Hydraulic Unit or the ABS Modulator Valve ?
 
I'm out of ideas..about to take to a shop and have them go over everything..which I'm gonna hate. Cause I just know they'll try and sell me land in the desert for something that's an easy fix. Everything is completely new !
 
anyone have any suggestions..would be greatly appreciated
thx

It may be your ABS control. There is a company that rebuilds these here is the Link... http://www.absfixer.com/ It disconnects from frame fairly easy and still allows use of vehicle you just don't have ABS anymore it's like the old style brake systems at this point.
 
For the sake of a few dollars I would also replace the front rubber hose lines, a good flow with bleeding may not show a partial wall separation within which will hinder actual brake usage under pressure....my 2 cents worth.
I had hard pulling to left which turned out to be bad left rear caliper but you have already gone that route.
 
What ever you do DO NOT let GM Sarah get involved, she is this forums site TROLL

Thx Rayt2, I haven't replaces the flex hydraulic lines yet..about the only thing I haven't replaced. I had someone on another forum say the same "to replace those lines", that they had a tendency to collapse on the inside. If I have the same results after I may have to go the ABS control route..about the only thing left..lol, thx again. Everything helps

I know this may be minor, but... have you ever given thought of it not being the LF brake? I have in past come across where one wheel is froze OPEN for whatever reason, and you get a pull to left because the RF caliper is froze open,etc. therefore making it feel/look like a pull to left when in fact it just pulling because its the only one working. You maybe have got there already but I figured I would throw it out there. Sometimes you just have to step back and look at it in different light. It also could be proportioning valve. You also should look at defective NEW parts. It happens from time to time.
Good Luck
