jeff, you?re breaking my heart out now. I replaced the Master 7 or 8 years ago. What makes you come to that conclusion or is it experience? I appreciate your input and yes that it could be a probable cause. Thanks

Experience.. question to help me diagnose

Go out to car, start it, depress brake, release depress again right away.

When depressing the brake note travel each time.. are they the same or different travel distances

Tested several times and the travel distance was the same.

In the comparison, I do know the wife?s Cadillac downshifts as it brakes which makes the braking system feels a lot better than me braking in the Z.

But thanks again for a way to eliminate the master cylinder.

I?ve had the Goodridge stainless brake lines for 12 years, helped quite a bit with soft pedal. At the time they were pretty reasonable $.

I have the same problem with my 90 zr1 ... the front tank is in the center and the rear is full ... if I put the correct level, after a few kilometers the rear is higher and the front lower ... the car is braking well (as far as I can understand).
Are there gasket kits to overhaul the master cylinder?

I already have stainless brake tube

Max,
Steve from Crossed Flag Performance and I have been trying to locate an overhaul kit for a while. There used to be a kit available, but there are none to be located at this time as best we can tell.
There are some replacement master cylinders available, but they are not visually the same as the original.
Only choice appears to be to replace with an aftermarket unit and keep your original to overhaul if someone comes up with a way to do it.
If someone has found a solution, maybe they will chime in. I know a few of us would love to find the solution.

Hello....
this is what i think you are searching for:

https://www.ebay.it/itm/172512514733...torefresh=true

It's incredible that isn't there any replacement kit for this kind of master cylinder....The PBR Factory doesn't exist anymore??

I also read on other forum the quality of aftermarket master cylinder is not very good...after 6/7 years they replace agayn the M/C....is it true? Is there a brand better than another? Suggestions??
