No brakes!! was created by MNM7
Hey guys

I replaced my rear brake pads over the weekend, had to refill brake fluid cylinder. I pumped the brake to see that the pistons work and put everything back. Now for some reason the pressure doesn't stay. i pump the pedal again until i can feel that it gets harder and i can feel that if i move the bike the brake works, but a few min later, it's got no pressure again. I don't see any leaks, the bleed valve is secured and closed. What could it be?

Sounds like there is still air in the system.

Yes, you will need to bleed it properly. Depress lever, open bleed valve, close bleed valve, release lever, repeat, repeat, repeat...

It is very important to open and close the valve before releasing the lever to avoid re-introducing air into the system.

Agree that it's most likely you still have air in the system... herewith a youtube guide on how to sort it B)

Hope this helps,

Pete

A good habit is to change fluid everytime you change the pads. Use a syringe to suck out all old fluid from reservoir and refill with new BEFORE you start he bleeding process. Also use the opportunity to clean around the piston and all slide pins with brake cleaner then re grease the pins to ensure caliper can move side to side freely.

I like to drink lots of beer??
