sammo[RL] Posted June 2, 2007 Report Share Posted June 2, 2007 I was wondering if anyone knows why my master cylinder in my 76 ke30 is playing up. What happens is the main fluid Reservoir (black lid) will empty its fulid and the secondery reservoir (red lid) will fill up to over-flowing. So what i have to do from time to time is take fluid from red, and put it into black, so the pedel doesn't go to the floor! Can it be fixed :bash: Quote Link to comment Share on other sites More sharing options...
Robert Posted June 2, 2007 Report Share Posted June 2, 2007 How low does your pedal normally go? When fluid is correct. Quote Link to comment Share on other sites More sharing options...
sammo[RL] Posted June 2, 2007 Author Report Share Posted June 2, 2007 Well...maybe a slight over enthusiastic statement, but i can defenitly feel the pedel go down when the first one emptys. As far as i know pedel travel is normal, about an inch, inch and a halve... Quote Link to comment Share on other sites More sharing options...

Basically each cylinder is fluid for either the rear or front braking circuit. What's probably happened is that a seal has gone in your master, and so whenever you put the brake on it pumps fluid from on circuit to the other, but it can't return. At least, this is what happened with my old Datto master. Sounds to me like it's time to get it rebuilt. Mike Quote Link to comment Share on other sites More sharing options...

Yeah i thought it would be something like a seal gone or leaking. You may be right...rebuild time.... Quote Link to comment Share on other sites More sharing options...
MRMOPARMAN Posted June 2, 2007 Report Share Posted June 2, 2007 yeah i agree, there will be a seal blown/broken in your master so its pumping all the fluid from the front circuit is returning to the rear when you let the pedal up. I'm suprised it hasnt affected the braking off the car. Quote Link to comment Share on other sites More sharing options...

snot35 Posted June 4, 2007 Report Share Posted June 4, 2007 Nope she pulls up fine... It's not actually the seals that are used in braking that's probably stuffed, it's more likely the seal that separates the two circuits in the master. It will probably pull up fine until all the fluid is gone. Either way, rebuild!! Mike Quote Link to comment Share on other sites More sharing options...
sammo[RL] Posted June 4, 2007 Author Report Share Posted June 4, 2007 It will probably pull up fine until all the fluid is gone.
