Re: Loosing brakes

does the lever firm up at all after use and cooled or after pumping the lever or has it just stay spongy

Re: Loosing brakes

How much fluid do you have on the pot?

You need to keep an air gap for the diaphragm to flex under hard breaking

Discs, which fuel and pads are you using?

sorry if you know this just putting ideas out there.

Re: Loosing brakes

It firms up when it cools , sbs street excel ,, brembo discs ... It was like it to start with ... So i changed pads. Fluid, calipers and discs , but not the lines ...
Its better than it was but still goes spongey ....

Re: Loosing brakes

Re: Loosing brakes

Try using motul rbf 600 brake fluid..........it's got a higher boiling temp.

I'd get braided lines too but would that really cause lever travel? :dunno1:

No signs of leaks from the m/c, right?
