Re: '99 taurus - Brake problem; long pedal travel and slow to stop
Alright guys, here's the update: and thanks for the thoughts so far...
I didn't have much time to check on things before it got dark, so, I did check for a vacuum leak. I pulled off a few vac lines to check for suction and there was sufficient suction at all ends. I never realized how deep the booster is installed..waaay down under the cowl.
I do have some pressure the first time I use the pedal, but upon the second try it goes straight into the firewall. I only drove up the street. Upon parking the car the brake pedal still had no travel. After I shut off the car and pumped the pedal a few times I gained a bit of pressure, but with some force I was able to put the pedal back toward the firewall.
The front brakes checked out good. I didn't have enough daylight to check the rears - yes, they are drums. The parking brake functions as it should and I couldn't see any abnormalities around the master cylinder/reservoir/booster that would have me think it's something mechanical.
I'm going to get it into the dealer, hopefully tomorrow, and get the brake fluid flushed as it's been 70K since I had it done it. Normally I just change out the reservoir fluid each time I check the brakes and replace pads/rotors/shoes. Dirty or plugged line(s) perhaps? Strange, but possible, in a 1 in a million sort of way.
Hopefully I'll be able to take a look at the drums tomorrow. But, would a broken retaining spring or clip cause this? Hmmm. When I put the brake pedal to the firewall the car came to a slow stop, but I didn't notice any pulling side to side which would have me believe that a certain wheel was the culprit. Then again, the proportioning valve might be doing its job here to keep the car straight as it undoubtedly 'thinks' when I put the pedal into the firewall that I want to make a panic stop, but in reality, it feels like I'm trying to brake the car going downhill with a 6000lb trailer attached.
It has me a bit puzzled. I do need to wash the engine though, it's frg'n dirty under there from this long winter.
Any more ideas guys send them my way! I'd like to know what I'm getting into more to fix it myself (if possible). Last case is to send it into the dealer, which I will call tomorrow to at least get an appointment. It's a busy place so it'll be at least Thursday I'm sure, before it'll be looked at, which gives me time to tear apart the drums. Wouldn't my luck have it, I can't locate my repair manual ANYWHERE.
