I have bled my brakes efficiently and right but still have spongy brakes. Should I rebuild the master cylinder? Pads are in spec, discs are in spec. Cailpers do brake at full capacity with no leaks but I have to pump them to get max brakes. Bike is almost done but I'm not going to ride it in this condition as front brakes account for 70% stopping power. Help please. Don't know how to rebuild a master cylinder either lol

 

Buy a new one.

 

a rebuild kit only costs 32$ at k&l supply and are oem sourced parts. a new master cylinder costs 209$ I believe at bikebandit.com. my desire is to find a write up/tutorial and just rebuild it. does anyone have a good link to a good tutorial? I have all the right tools to complete the job. (though my mighty vac went missing.) I'll just bleed by lever.

 

I'll try not to sound harsh when I ask this.

If you knew what you wanted to do when you asked, why did you ask?

 

I did more more research after asking. not to be a bother.
