My passenger side brake locks up. Shakes really bad! HELP!

[crazymonkey0810]

I have replaced both front calipers and hoses on my Infiniti G20 but yet my brakes still seem to lock up and causes a lot of resistance. It shakes like crazy and freaks my daughter out. Usually happens on the highway. I heard something about a check valve on the brake booster... Does anyone have any ideas as to what it could be? I'm tired of spending money on this thing and not fixing the issue.

It shouldn't be the check valve on the brake booster, that would only affect your power brakes.

Does the pedal feel normal when its pressed? How do you get it to "un-stick"? It could be your master cylinder.

[crazymonkey0810]

The pedal gets extremely hard. I'm seeing quite a lot of other prior with similar issues.

[crazymonkey0810]

it eventually comes unstuck in its own. Usually agree I stop for a few minutes and turn it off.

Well the shaking is definitely warped rotors undoubtedly caused by overheating them with frozen calipers/brakes stuck on.

If the pedal is extremely hard and you have to push it REALLY hard to get the car to slow down, then yeah, you probably have a problem with the power brake system (booster). Otherwise, it sounds like you're going to have to go in to do some exploratory surgery into the master cylinder/brake booster.

Papa Smurf advise is good. With brakes if you don't know what your doing you might take it to a shop for safety's sake.

Brakes and steering are the 2 most important things on a vehicle.
