ac and brakes

titokang · Jan 21, 2010

Well my cars treating me bad again. While driving home from school yesterday i noticed the ac would cut off from the center vents and blow more from the side vents when given gas, and would stop when i let go? I aint a mechanic but know some stuff so no idea there. And when i parked my car i was gonna check tire pressure on my passenger front and there was brake fluid all over my wheel and splattered across the passenger side and the brakes were hard. Will a rebuild fix it or just buy a caliper, lines seem ok.

The AC registers on the center and sides are all funneled to the same place, so gas/brake will not affect it. What you may have been feeling was it transitioning to the defrost vents, which simply means you need to inspect the small vacuum line protruding from the passenger side of the firewall and moving along the pinchweld to the driver side where the vacuum tree is.

As far as brakes, if you are leaking that much fluid, your brakes wouldn't work at all.

The first seems like a vacuum line giving you problems.

The second, does it seem like a piston blew?

When you brake does it pull one way?

Hold the brakes down, does it eventually go farther down then it should?

My whole passenger side was covered and washed it immediately. They were really hard to push and it was hard to stop the car, i pretty much pressed it all the was down to get it to stop and that took awhile. i havent had time to check it its on a jack stand and i get home too late from school to see exactly where its coming from as its totally drenched and full of dirt from the drive. But i also didnt notice a pull cause i replaced the driver side tire and it pulls to the right cause its more inflated. thanks

check fluid. bleed the brakes. find a leek if any.

stop driving it till you get the brakes fixed!!!
what year of car do you have?
94/95's have a brake booster that operates off of vacuum.
The a/c vents also operates off of vacuum.
Acceleration is optional, stopping is mandatory!
get the brakes fixed. we don't want to see you in a thread where you wrecked the stang.

well i check it last night and i had a twist in the line like it actually formed a loop, is that normal? well i unlooped it and i drove it back and forth on the driveway and it was leaking from the connection to the caliper. I tightened it up and bled the brakes but it hasnt leaked but im just paranoid, i think too much haha. Anyone ever have a twist like that? Would a twist cause it to leak maybe from too much pressure?

it may have kinked the line when you turned.
I wouldn't think there should be a loop in the line. maybe someone had to install 1 that was too long and needed to put a loop in it.
Keep a close eye on it. No leaks allowed.
How was the pedal feel in the driveway? It shouldn't be hard but still feel solid.

Well it doesn't feel hard now but solid like you said but its time for pads, and the rotor that this happened to needs to be cut cause its very uneven wuth grooves. I won't be able to do it till Tuesday so I'm not gonna drive it till then. If any more problems come up ill let you guys know. Thanks
