hi i got a lack of pressure when i brake. But this happen only at the first try. Ten, i have to pump the pedal and it's ok, it doesn't loose it's pressure as long as i keep braking.

I got a subaru 4wd 93. 243 000km.

If anyone can give me a hand..

Thx.

down.

Start simple..Check your brake fluid level...might be low.as breaks wear the fluid level drops due to the plungers on the calipers expanding..Could just be some air in your lines..Try bleeding them first. Check for a leak in a wheel cylinder also.

 

Hope that helps.
