Brake MC question

[formeRiceR]

What are some signs that the brake master cylinder is going???

question, okay if you have to pump the brake like 3 times before the brakes start clamping, and after those 3 pumps there is no movement of the pedal, that means there is air in the lines right??? and not a bad MC...

Could be air in the lines. But it could also mean a bad or worn out seal inside the master cylinder. You could tell if you have a leak when you step on the brake pedal and tiny air bubbles surface to the top of the reservoir.

Try thoroughly bleeding your brakes first before you start replacing things. I hope this helps..
