Re: Brake drag
Could be any number of three things.
1) Frozen Slider. To check this unbolt one of the caliper bolts, roll the calliper up and take out the pads. put the calliper back down and the bolt back in. Try sliding the caliper back and forth on the sliders. If it doesnt really move then youve got a frozen Slider.
2) Frozen caliper. To check for this. pop the cap on your master cylinder first (ill explain why), and use a prybar/channel locks/C clamp to depress the piston in the calliper. If you have a pretty hard time making it press back in, then most likely the piston is froze and you need a new calliper. If you try and press the calliper in while the master cylinder cap is still on you risk blowing the master cylinder, not to mention making it harder to push the calliper piston back in.
3) Brake hose has collapsed. There isnt a really good way to check this. You have to unbolt the line from the back of the calliper, and let it bleed for a little bit. If it bleeds at a pretty consistant flow, and not slow and drippy then your line is okay, if its sluggish then it needs to be replaced. Brake lines should really always be replaced in conjunction with callipers...its extra security and one less thing to deal with in the future.
hope this helped.
