I rode the bike

I rode the bike for the first time. Can't really tell what issues might be except for my front brakes keep locking down. I am not really sure what is wrong with the brakes unless I need new lines and possibly the master cylinder needs rebuilding. Aggravating as every thing works on it until I pull the bike out of the building and ride. Well I have had it this long without riding it, might as well wait a little longer and get it right.

Grace and Peace to you!
Richard

Might have rings of crud around the pistons in the calipers

if I pull the cylinders out of the caliper, what am I going to see? Will I destroy anything and have to replace it?

Did you verify fluid was squirting back up into the master cylinder through the tiny hole when you released the brake level?

If you pump the brake lever until the piston comes out, what you will find is a bunch of fluid behind it. You can empty it and clean everything. There should be 2 rubber rings in each cylinder.

You know I did do that. I pumped the piston until it showed good clean cylinder but didn't clean the crude off. I guess I will do that.

Also I didn't see anything coming back out the master cylinder. I am thinking that since one side works that the master cylinder is working for at least one side, maybe I need to clean that hole a little more. Don't know but worth a try.

Grace and Peace to you!

I've been suggesting for at least a week to clean out the little hole and ensure fluid comes back out of it. When I was having brake problems I could get the left side piston to push in with a clamp pretty easily but I could not budge the right side no matter how hard I tried.

Could you get the left side to release also after pressing the lever and releasing it? Also I took your advice and cleaned that hole but apparently I didn't clean it enough. Do I need to take the fluid out and clean it or just stick something down there to clean it?

Grace and Peace to you!

The left side was not clamping tight to the caliper like the llrightbside was. I also believed I had cleaned the hole well, but I had to do it a second time. I had all clean fluid the second time. I stuck a needle in the hole as deep as I could several times and haven't had any problems since. I could be wrong. This may not be your problem. But your symptoms are exactly like mine. Sorry if my previous post seemed rude. I had a stressful morning at work, so my apologies.
