Need Help With My Brakes?

[steeves_ca18det]

Ok i have a 89 180sx. When i drive the car for around half an hour on a hot day my brakes lock up. But if i drive it around on a cold day nothing happins. Could this be my mastercylinder or brake booster.

I bet you need to grease up your calipers, as things expand and get hotter then they start to seize up....

kind of weird problem. Do you mean a caliper hangs up, brakes lock up when you hit the brakes normally, front or rear? I would check the pins for the brakes, make sure they aren't rusted in the caliper. Also might be a hard line or rubber caliper line may be almost clogged.

I agree! Brake fluid is kind of like the hydraulic fluid they use in municipal machinery, and I know for a fact that heat makes that biatch expand...alot.

A good flush of the system might unclog a bunch of junk.

Following "574-240sx" are the calipers hanging up or are the brakes loacking when you touch the peddle and release when you let off the peddle?

If case 2 probably the cheapest and easiest thing to do is check the brake pads...a lot of times when they get glazed over, break-pads tend to do weird things. The same thing happened to my pick-up. If that doesnt work just trouble shoot accordingly. (remember that it doesnt hurt to replace something cheap even if it didnt fix the problem....prevents later failures).

Ok so what happen's was this, i replaced the front brakes a little while ago. I did a full flush of the system. It worked great for about a week or two and now all four are locking up. It only happens when it is really hot out. Because when i drive to work in the morning its all good but when i drive home i barly make it home. The pedal is hard and the brakes are on constitly.

sand the rust of the sliders and ues a bit of axel greese on the slide pins only avoide greasing any thing else because it can get on pads and rotors also try rebleeding system
