Adjusting Rear Foot Brake

My rear foot brake doesn't work it just sinks to the floor when you step on it. In the manual, it says it is a mechanical floating disc brake. How do I adjust it to make it work? There is a rod that goes into a box and there is a nut which looks like you can adjust it, I am just not sure how. Also, there is a brake fluid line coming from the reservoir on the handlebars to it.

They're not adjustable. Just works off of hydraulic pressure like most other brakes. Possibly time to change the fluid and bleed the lines, or the master cylinder could have gone out on you.

Well the foot pedal/rear brake may not be adjustable...The rear brakes are!
When installing new pads on my '00 TB I found I had to adjust the spacing on the pads with the caliper. At first I did not realize this and threw the pads in and buttoned it up.... I had NO pedal!! I took it back apart and looked at what I had done and found I needed to "screw" in the caliper to a correct distance between the pads and disc. Once accomplished, I had a pretty good pedal again....

Have you changed the pads? Do you have a manual? Its all outlined there.

My 98 xplorer has one, there should be a bolt with a jam nut on it, loosen the jam nut, turn the bolt in (both need 7/16" wrenches) till you have a good pedal, then tighten the jam nut. I believe there is even a spec for it, not sure what it is though, just make sure the brake doesn't drag.

My 01 Trail Boss sunk to the floor. I had to bleed the line and it worked great. The line at the bleeder was plugged, so had to clean that out first.

If a 99 is like my 01, the hand brake is on the left handlebar and has it's own reservoir. It's bleeder is the one on the left on the rear axle. The hand brake controls both front wheels and the rear axle.
The foot brake is on the right side and has it's reservoir about ankle high behind a cover. It's bleeder is the one on the right. It only brakes the rear axle.
The bleeders are a fitting inside a nut. Hold the nut with a wrench and loosen the fitting with another wrench. The first time we did mine, we turned the nut and fluid came up around the threads. Then we figured out that there was another fitting inside that nut.

nice work. I think i am having the same issue. My pedal is to the floor, it still stops the brakes when i apply it but it doesn't seem to spring back up. My question is should the aux brake pedal rise back up after applying it like on a motorcycle or does the pedal move down as the brakes wear?

Thanks for any info.

Wow, blast from the past! It should spring back up. When it is sprung up, the top of the pedal should be parallel with the foot rest.

I figured it should. I'll have to check the manual but does anyone remember where the spring it that brings it back up? Or should the hydrolic pressure bring it back up?

Thanks for the reply.
