I took my 650 out last weekend for some fun in the sun and noticed that my front right brake wasnt working. The brake handle was not as firm as I remember, it seems to be easier to squeeze.

Could it be the master cylinder, piston in the caliper, bad fluid, air in the fluid or a combination of any or all? I see no leaks anywhere even when squeezing the brake.

Thanks!

 

I would say first check to see if you have air in the lines or are low on fluid...If you aren't how are your pads and I would say if all of this is fine and your brake lines are sealed and have no leaks or anything I would say either the plunger went bad in the master cylinder or you need a new caliper or both calipers.

 

Thanks for the reply, I will look into your suggestions. I havent looked yet into the calipers yet, but can you replace the pistons in them like you can in cars or do you have to buy a whole new caliper?

Good ? um you may be able to, but would prob be better off just buying a new one or used one from ebay.
