Had to ride trial with no rear brake yesterday. I think I have found the problem but I was wondering if anyone has any tips on bleeding the system. thanks

Allow yourself plenty of time for job, and make sure you are in a good mood to start with it may not last long not had the pleasure of doing one yet but have heard they can be abit tricky

I'll ask dad tonight and see what the secret is for you, hes done loads

This guide is very thorough with lots of color photos. It's from Sherco but it applies to all bikes.

back bleed it , use a syringe with a small tight fitting bit of rubber pipe on the end. fill the syringe with brake fluid, push the pipe onto the bleed nipple , and after taking the cap off the master cylinder and placing something under it to catch the displaced fluid, gently push the fluid through, you will have to experiment withn how much to open the bleed nipple but 3/4 of a turn is usually enough. repeat until the fluid in the master cylinder is clean. hope this helps.

Hi, Just to say I agree with Paul W; Back Bleeding is by far the best way to get fresh fluid in and air bubbles out. Just keep an eye on the caliper to make sure brake fluid doesn't seep out of nipple and onto the brake pads. Also if you're buying brake fluid, get the smallest bottle possible, open just before use, bleed both brakes and then chuck the rest. Old brake fluid absorbs water and doesn't work half as well as fresh stuff each time, so well worth using new stuff each time.

We've done afew of these and be careful about trying to back bleed a Beta rear brake as some models have a ballbearing in place to stop too much stuff entering via the bleed nipple. After all it is for expelling rather than intake.

The best Way is to disconnect the rod from the rear brake pedal then use a screwdriver or similar to activate the plunger on the master cylinder and bleed conventionaly. The advantage of thi is because the brake pedal only moves the plunger afraction of its potential movement and it there fore takes forever/never!! tobleedit through.

I'm pretty sure this is the best way as Johnboy himself helped me out when we had the same problem.

Good luck

Thanks everyone , I managed it the conventional method and everything went well which worries me a little

I found it bled ok if I backed the rod right off so the cylinder used a lot of travel. Now I have a firm lever but the brake is still average at best, even new pads.

Well named - bleedin' Beta brakes!
