Ok guys, I have allot of stuff on my bonnie fixed, but after i got the harmonic balancer fixed I seem to notice another problem. I should note as I mention in another post I have some kind of brake fluid leak (pretty sure) and when i press the pedal it goes half way to the floor and then the brakes work. I notice that when i pump the brake pedal a few times in park or neutral (while there is no load on the trans) that the pressure on the pedla increases and RPM'* seem to change (go up) is this a vaccum leak? I have a feeling it is. Or maybe a brake booster, but that would explain the leak, or would it? I know there is no fluid on the firewall.

Edit: I also whated to add that it seems my trans will not lock the torque converter until 47 -50 MPH, is this normal? Or would this be a symtom of a vac leak? It shift and drives fine, sometimes it does rev up a little before locking.

thanks for the input,
Chris

Not as likely to be a vacuum leak as it is dirty fluid or old tired friction material. Check the condition of your trans fluid after driving a couple miles. If it'* not nice and pink, consider a flush or a pan/filter drop.

Thanks Bill,

what about the brakes? Does that seem like a vaccum leak and where?

Check the rear drums (brake cylinders) for leaking. And consider bleeding your brakes. That may be all that'* necessary.

A vacuum leak at the booster will make it harder to apply the brakes, not easier.

I will check tonight. what about when I pump the pedla a few time and the pressure builds up, does that make sence that engine RPM would go up???

Brake pedal coming up as you pump the brakes is a symptom of a leak or more commonly, a bad master cylinder. Another symptom of a bad master cylinder would be if, after you pump up the pedal, with steady pressure on the pedal, it gradually moves toward the floorboard. If the fluid level in the master cylinder reservoir is not dropping (indicating a leak somewhere), the problem is probably the master cylinder. But, check for leaks first. Look at the rubber hoses to the front calipers for leaks, and trace the lines from the master cylinder to the rear wheel cylinders looking for leaks. Look on the inside of the rear wheels for evidence of leaking brake fluid.

I seen that Bill mentioned that above, but my fluid leak is more tword the front of the car, I see a oil leak (oil pan gasket) and right around that area there is a brake fluid leak as well. So i would suspect that it is either from the master cylinder or the brake on the drivers front side.
