1998 Isuzu Rodeo Question 6 cyl Front Wheel Drive Automatic 205K miles
Brought my 1998 Rodeo to the Isuzu dealership about 2 weeks ago because the brake pedal when you apply pressure moved almost to the floor. Was told initially that it needed a new brake booster. Told them OK replace. Truck won't be ready till the next day because they needed parts. Got called next day and was told that they found that the master cylinder had a "small leak" when they bled the fluids out and that would need replacing. Sd OK, go ahead. When I picked the truck up was told I would see a big difference in how the brakes/pedal felt. Boy I sure did! When I touched the brake pedal I thought I would go through the windshield.
Drove truck home no problems. Next day took it out. After driving few miles I was having difficulty getting truck to drive forward when I pushed on the gas pedal. Truck just about stopped when I let up on the gas. Called the dealership back while I was driving was told to bring truck back in. Told them no way goiing to make it. I would have it towed. Went right home and by the time I got there I had smoke coming from under the truck, wheels/rims burning hot to touch.
Had towed to dealership. Got call from them saying that because master cyclinder wasn't working properly for awhile that my rear brakes were not being used to their full extent. Rust got in there and because the master cyclinder is now working properly the rust is being pushed through and causing the brakes to freeze up. I would need new rear brakes. They said I have about 2-3mm left on the pads.
They said they checked the front brakes and they are OK. They were able to free up the brakes and it was OK to drive but I should not wait past my next oil change. They said they noticed the rust when they worked on my truck but did not mention to me-forgot. I called two mechanics who both said they think they did not adjust the free play after replacing the master cyclinder. They wonder if I even needed the brake booster replaced. The dealership told me you can't adjust free play with disc brakes.
Now the brake pedal is acting like it did before I brought it in to have it fixed 2 weeks ago. Any idea what may be going on? I was told by the dealership that it isn't fair to ask opinions of other mechanics when they were not the ones who were working on the car to see exactly what was going on.
