i put new calipers and new wheel cylinders on my 1990 dodge diesel w250 blead air out. then re bleed after driving for 1 week and no more air comes out but brake fluid leaks out the top of the master cylinder even know the cap on it is very tight and rubber seals any ideas.

 

I'd say overfilled.

 

my new massa cyl on my 93 ctd was leakin last week.

I removed the clamp and crimped it a bit snugger with my frickin huge channel locks


snaped it back over the cover and sprayed the massa cyl housing and surrounding area down to remove the brake fluid before it eats anything...
