My vehicle is a 2000 Chevy Silverado 1500, extended cab shortbed with a 4.8 litre engine.
Just read my post and realized how long it is. I know many don't have time to read all my headaches, but I'll leave it here just for information. My issue is that I have replaced every piece of my brake system but no matter what is tried we can get no pedal pressure - the brakes work fine, just not something I want my son to learn to drive with.
1) New master cylinder (Not refurb) 2) New stainless steel lines, from the master to ABS to all four corners 3) New ABS Control module and New ABS pump (Not refurb) 4) New pads, new Rotors and new Calipers at all four corners
There are no leaks to be found any longer, I have been over the system as well as the current mechanic. His only suggestion at this point is that I have a bad master cylinder. This is the third master to be put on the truck during this trying time, so I am having a hard time swallowing this diagnosis, but if that is it, then so be it. Does anyone have any ideas as to what could be the issue? Any and all help would be most appreciated.
Thanks in advance for any and all help, MJ
A couple years back, 2013, I had to make a sudden stop when a state trooper did a u-turn right in front of me. When I hit the brakes, the pedal went to the floor. As it turned out, I had blown out one of the steel hard lines. I took it to a mechanic and asked them to replace the blown line and to replace any others that appeared to be ready to go, too. In the end, the mechanic only changed the blown line but since I needed the vehicle I had to take it. Everything was fine for a few months, then another line went. I took it to another garage and asked them to replace ALL the hard lines. After having my truck for about a week, it turned out they also did not replace all the lines as requested, but only changed the one front line that blew out. Again, I took the vehicle and went on my way kinda perturbed. Since that time I have hired three more mechanics to change out all the hard lines, even going as far as purchasing a whole kit of stainless steel lines, pre-bent. The first mechanic totally hosed the whole thing, had my truck for months (seriously!) and all he did was run new lines to the front of the truck. Problem was, instead of using the proper lines (everything in the kit was pre=bent and marked), he cut up the long lines that should have run to the back of the truck to do the fronts. After this fiasco, I found another shop going so far as to speak to the owner, explain all the issues I have had in trying to get this job done and he assured me that he could do the job, he was a GM mechanic for 25 years before starting his own shop. I bought another set of stainless steel lines and dropped everything off to him. He told me that the job would cost $500 and be completed in two days.
Two weeks later, the lines were on the truck but he could not get any pedal pressure. He also indicated that he could not seem to get much fluid flowing to the back lines even though he had spent days trying to bleed the system. He determined that the master cylinder was bad - it was brand new. I contacted the manufacturer and they shipped me a new, not refurbished, master cylinder for my truck. It was put on but it did not solve the problem. Then I was told that it must be the ABS system. I purchased a new, not reman, ABS pump and he installed it. Surprise, same issue. I had gotten so irritated at this point that I paid him the $1300 for the work he did and took my truck. I found after getting home that there was a leak at the front line coming out of the master cylinder. I took it back to this guys shop and he kept the truck for another two days. In the end he said that the lines must be bad, he can't make the leak stop.
The truck sat for just about a year, but since my son is ready to start driving I needed to get the truck right since he cant drive my car, manual transmission and too powerful. I hired yet another mechanic, one from my place of employment. He fixed the leak at the master but found that he too was unable to get any pedal. In addition to fixing the leak, he put on new pads and rotors on all four corners. He checked the vacuum booster but it was not the issue. He suggested the master but I told him that the one currently on the truck would be the third new, not rebuilt, in the past year and a half. As it turned out, the only other thing that had not been replaced was the ABS controller. I hated to even entertain making that purchase, but in the end I did and the mechanic installed it, to no avail. He agrees that this should not be so hard to solve, has looked at the whole system for leaks, none. The only other thing he can suggest is that I have a defective master. I want so bad to just buy it and have all this behind me, but dang, how many times do I need to buy one and why after replacing everything in the braking system (except the brake booster) is this still not working.
I've been sitting here for a few days now, scouring the internet looking for answers. Found similar issues, but in the end these folks find their gremlin and all is right in their world. Does anyone have any other thoughts on what could be wrong? Any help would be more appreciated than you could ever know.
