2004 Dodge Caravan 6 cyl Front Wheel Drive Automatic 145, 00 miles
Hi, I put new pads & rotors on the front of my 2004 Grand Caravan ( front disc / rear drum ). Which I've done a few tmes before with no problems. Until now. I started at right front, took the caliper off, pads off and proceeded to push the piston back in with a c-clamp. After I did that successfully, I remembered that I didn't remove the master cylinder cap. Thinking there was no harm done, I finished the r/f brakes, proceeded to do the L/F but, decided to remove the M/C cap before pushing the piston in. Finished the L/F brakes no problem. Went to back out of the garage and the brakes would not " pump up"! OK, that never happened before, so I decided to bleed just the front, figuring the rears weren't affected and actuslly, I'm not quite sure how air would've gotten in the lines anyway. Aggravation sets in and I figured to bring it to a garage to let them look at it. The garage said it was a bad master cylinder. They installed a new cylinder, checked the rear brakes, bled all the brakes and said the pedal was good. Wonderful! I hop in the car start it and the pedal goes right to the floor! Wait, I shouldn't say that exactly because while I do have SOME braking, the pedal is spongy and when I keep my foot on it (say at a light) it will keep the braking but, the pedal will " weep" down to the floor? Bring it back to the garage and they say it has to be a bad M/C. OK, I'll buy that so, I leave it for 2 days and they call and say " we brought the car in the bay and the pedal pumped-up fine but, we noticed a " grabbing" on the R/R wheel, which we found was a blown wheel cylinder, which we replaced, bled the system, drove it around and it's working great. It wasn't a bad M/C afterall" OK, now they got it! Picked it up, after hours and wouldn't you know it. The same FREAKIN' problem is happening as when I first drove it in! I am totally baffled! I am getting braking but, the pedal is drifting rapidly to the floor! Is there any way it could be that the BRAND NEW master cylinder is still bad (entirely possible) or could it somehow be a bad brake booster? I'm at a loss and apparently so is the garage! I apologize that the donation isn't super high ( which I'm sorry for) but this brake problem is rapidly draining our finances. Which are slim to begin with.I sure would appreciate any help you could provide! Thank you.
