Im not getting any clutch or brake pressure! WTF!

Ive bled the brakes and still have to pump them 4 or 5 times to brake safely, and I have to pump my clutch every once in a while(especially during in-town driving) to keep from grinding gears.

Ive got a good pressure plate, Im just not getting pressure in the pedal.

Im not loosinng fluid in either resevoir.



Are these problems connected?



Wouldnt I loose fluid if I needed a new booster?



How would I adjust the clutch pressure?



HELP!

they cant be connected, becuase they are seperate. you need both master cylinders and recheck

https://www.nopistons.com/forums/pub..._DIR#>/dry.png GREAT.....JUST GREAT.

No way to test them to to make sure?

I have the parts on my other cars....just dont want to take them off for nothing.

I think I remember having trouble with the clutches with my other cars too. Are they prone to problems? Leaking or Loose fittings somewhere?

Hope you get it figured. I'm having same prob with my Clutch on my 88

Ive heard(or read rather) That the lines are too small and replacing them with 1/4 or 5/16 helps....anybody know if this is true who can explain why?

its common for 20 year old hydraulics to be bad

You got that right. My MG Midget has fluid dripping down the pedals. I'm collecting it for now in a plastic FB rear window wiper cover. https://www.nopistons.com/forums/pub...IR#>/smile.png

But I cant find any leaks. Maybe I'll look again.

When my master cylinder went out a while back I had the same scenario. You had to pump the brake pedal in order to build up pressure. Through Victoria British brake master cylinders are $69.99 and clutch master cylinders are $39.95 so it won't put you back too much.

I had the same problem one time. No visible sign of leakage, but couldn't get any pressure. When I pulled off the master cylinder, it was apparently leaking around the seals, because where the rod is put into the back of the mc, it was wet and corroded. Replaced it and no problem. Never heard about the lines being too small.
