So I just changed my rear 400ex brakes, and its the the first time ive ever done it. I was pretty sure i did it right and when i tried to used them they arent very strong at all. They doing a tiny little bit. I dont know whats wrong!!!

Have you adjusted them, and did you get any oil or grease on the pads or drum when you reassembled them?

The brakes should be adjusted so that you feel some resistance when you turn the wheel. Not a lot of resistance, but it shouldn't turn completely freely. In other words, adjust the brakes to where you feel the pads begin to rub, and then back it off a hair.

how do I adjust them?

I'm not familiar with that machine, but I would guess there is a wing nut where the cable attaches to the brake lever. Turn that clockwise to tighten it.

Look in your manual for details.

I cant find it.... and the manual just tells how to adjust the parking brake.

Take a picture of the rear brake assembly and post it for us.

Or, look through the forums for similar threads, someone has recently posted pictures of how to adjust brakes.

ADDED: Helmut gave you a link to a manual in your other thread!

OK, They're hydraulic disc brakes, have you bled them properly and filled the fluid?

Here is the instructions from the repair manual. Look over it and make sure you didn't do anything wrong. If you took any lines loose, then you will have to fill it back up with fluid and bleed them. If you had a low pedal or lever to begin with, then you might have to bleed them.

They probly need to be Bleed!!!!

 

[dhen]

i did all of that right, i think i may need to bleed them? is that difficult?

 

[Helmut]

No, it's not hard to bleed the brakes. This might help. On down the page, it shows how to bleed without the brake bleeder pump.
