Thread: bad master cylinder?

Just wanted to see if theres any other possibilities before I change the master cylinder.

Symptoms: So starting today when I go to brake, there wont be much braking force on the 1st pump, second pump, full stopping power.

To come to my conclusion, I bled all the brakes, all brake hoses seem in good working order; not worn or possible leaking.
I dont see any leaks anywhere around the master cylinder either

It probably is the master cylinder, but old fluid can do that. I assume you used new fluid when you bled the lines though. The other thing is the rubber lines can expand under hard braking, but it usually takes them getting hot before it starts to feel this way. If after changing the MC it still feels this way, get SS brake lines, and you'll be solid. Heck, do it all at the same time.

The same goes for the clutch, btw.

yeah this is doing it cold/warm/hot anytime. and it happened all at once, not gradually (unlike like the clutch line). idk if one day its just gonna stop on me, so i dont really wanna drive it until its fixed. yes new synthetic dot3 fluid.

Just trying to think of something else that could be wrong....do you think a piston could be sticking? causing similar conditions?

Usually when a piston sticks people don't notice. You would get a hot wheel and poor mpgs, I don't think what yu described is a Sruck piston

cool, well my mpg right now is 31 and havent had wheel hop in a couple years. and i did notice, so i suppose its not caliper issue then
