Brakes

[z250kid]

Everyonce in a while when i brake i push down and it feels like im not going to stop i let up and push down and its fine. I have replaced front brake pads and calipers Front brake lines, hoses and booster. The rear end i checked the shoes there good and replaced the hose. I dont know why it does it. I have prebent ss brake lines for rear but spring theyll go in. And i have a new abs unit.

sounds like you need to bleed the brakes again or maybe you have a tiny leak.

Is the pedal too soft, or too hard, when this happens?

Is your air only blowing from defrost? Have you checked the vacuum pump at all?

[z250kid]

Replaced that after going through 3 of them i bought a ford one.

Sounds to me like u have an air bubble but that would make a soft peddle. Wonder if your vacuum assist pack is going bad.

Vacum pack? Where is that. I replaced booster and vacuum pump. It doesnt get soft when you depress it the pedal is hard. Feels like its not going to stop. But you let off reapply and golden

Can i just do a hydroboost set up. All i would need is a new booster and two lines right?
