Excessive brake pedal travel

Post by 754 » Sun Jun 30, 2019 9:23 am



Hey everyone,

I have a question for y'all, I have bled the linked brakes on my wing twice now (first time was because after sitting for 6 years they leaked down) second time was just to see if I could get a shorter range of travel. I didn't get much change when I bled them a second time, it travels at least an inch or more and requires tipping my foot quite a bit. I feel the travel should be shorter than that. I bled the brakes the old school way both times, having someone pump the pedal for me. Does this system benefit more from pressurized bleeding? Or are there some other bleeding tips I don't know about? As always an tips and info are greatly appreciated.

Travis

Try spreading the pads on both calipers so the pistons are all the way retracted, it will probably require you to suck some fluid out of the reservoir, and add some as you pump the brakes back up. Any air in the lines should be forced back to the reservoir.

Also, I have not seen the position of the bleeder screw on the front caliper, but if it isn't the absolute highest point on the caliper there will be air trapped above it. Some bikes sometimes require caliper removal and for you to hold it just so while bleeding.

Cheers.

It could also just be time to rebuild either the caliper or master cylinder (or both), or you could have a brake line that is swelling and reaching its end of life.

I had that problem on both front rubber brake lines on a 2000 Taurus except that they swelled shut. Boy did that thing sway during a hard brake! Stops nicely after replacing.
My foot pedal on my Wing seems to have a bit more travel than I like as well. Thanks for the tip, WA!
