Excess Impulse
XS400 Addict
I have a 1980 XS400 , I have rebuilt the caliper with new seals, cleaned up the piston, rebuilt the master cylinder, have new brake pads, and have all new brake fluid in it. It is Okay to use DOT 4 fluid isn't it? After doing the rebuilds it was a challenge to get the air out but was able to finally by using a hand held bleeder. On the 1st test ride after work was finished I noticed the front brake dragging hard, and I squeezed the brake lever and cracked the bleeder, this solved it. Today was the 2nd time I have really ridden the bike out on the road as I have been working on it off and on for the past year or so. Once again the brake started dragging, rotor was hot and brake was squeaking. My question is, is this just dirt in the system yet, is it trapped air? I sure don't want the brake locking up on me. I did apply the brake and crack the bleeder again and the brake released, but have a feeling this will keep happening. Any suggestions?
