Bleeding brake lines is one of those things that can be either really easy or a pain in the ass. Depending on the tool, you sometimes wish you had a third arm. But a number of options are now available to keep it from being the equivalent of a root canal.
We found said options all available on Bike Bandit, but these are readily available elsewhere.
The Speed Bleeder — this tiny little device replaces the bleeder screw on the caliper and stays on your bike 24/7. They come with a check valve inside that lets the fluid out without letting air thus eliminating the need for a second body to open and close the bleeder screw. To use a speed bleeder, just attach a simple rubber tube with the catch can, open the speed bleeder by turning it a quarter-turn, and pump the brake lever. When your fluid has been completely flushed, just close up the speed bleeder, remove the tube, top off the reservoir, replace the reservoir cover, pump the brakes a few times, and you’re on your way. COST: $16.95
The Brake Bleeder Tool — better than the plain rubber tube you might be used to using, this actually has a check valve in the middle of the tube that lets the brake fluid out without letting air in. No more opening and closing the bleeder screw as you pump the brake lever. After the fluid has been let out, close the bleeder screw, remove the tube, and do the same thing to the other caliper if your bike has two on the front wheel. Repeat this process until you see that the fluid is clear and contains no bubbles. Top off the brake fluid and replace the reservoir diaphragm and cover. COST: $16.95
Brake Bleeding Vacuum Kit — kits like this come with a rubber tube that attaches to a catch can and then to a vacuum chamber and a hand pump. Attach the tube to the bleeder nipple and then use the pump to build pressure that sucks the brake fluid out of the system and down the hose. Once you open the bleeder screw, the fluid will begin to come out of the caliper without having to hold down the brake lever. You will have to still make a trip up to your handlebars every few moments to check the fluid level in the reservoir so it doesn’t run dry. After the fluid has be let out for a few moments, close the bleeder screw, remove the tube and do the same thing to the caliper on the other side. Repeat the same process as you would with the Brake Bleeder Tool and you’re set. COST: $32.99
