For some reason when I stop at a light or for a lengthy period. My brake pedal will slowly keep going to the floor. I checked for leaks on the ground and checked the fluid level and both seem fine.

I did get some new tires put on the other day and the guy said there was a big puddle of fluid on the ground after he was done. Could it have been something he did with the jack? It didn't seem to do it before then.


I have a 88 vert NA.

 

If the brake fluid seems fine and doesnt go down after like 20-30 times of pumping it, then its the master cylinder.

 

Ok. It didn't go down at all since yesterday. I guess I'll order a new cylinder tomorrow.

Thanks for the fast reply.
