Check the upper suspension mount in the mudguard at the top of the shock absorber. It is a large rubber mount held in by 3 bolts. They have a habit if breaking and allowing the shocky/steering mount to move around. Test by jacking the car off the ground and watch for down wards movement of the rubber. I have known then to allow the whole unit to drop out .

SOURCE: 2004 Saturn VUE AWD V6 has a harsh grinding sound in front wheels

Have you checked your wheel bearings? When these go out you can get a harsh grinding noise. This sounds like that is what it might be. Does it happen when you are going fast/slow turning/going straight? I know you said it's inconsistent but the more info the better. However, if I had to bet, based on what you have already said, it's your wheel bearings. Let me know if you have further questions. Thanks for using FixYa!

SOURCE: Front Brake Pads locked up on Rotor

Have the brake pads been so very work they are down to the metal? This could cause the caliper piston to extend too far and not be able to retract properly.
Calipers Fail mostly from a cut in the rubber boot around the pistion dirt and debris get in there and rust the piston and it cannot retract properly Do they retract after they cool Down? if so the brake fluid has "boiled" if brake fluid is not changed about every 24,000 miles condensation builds up and lowers the boiling point of the brake fluid causing this problem.
Tell me does it happen after a long drive or siting a long time in heavy bumper to bumper traffic in hot summer weather? I recommend a complete brake fluid flush an change the calipers with NEW ones ot rebuilt and use dielectric grease on all points of metal to metal contact between the caliper an the mount bracket and thee ends of thee pada n the slide points they ride on and the pins that go through thecaliper and thread into the mount only dielectric not regular grease it will cause sticking and a worse problem than you have now.

SOURCE: Problem with break caliber and pedal and rotor 99 corolla

you might have a froze caliper piston, he is asking for all of that because whenever you change a caliper out you dont just want to change the caliper but do the brake job while you are there because more than likely the rest of your brakes are worn as well and if you just do the caliper you will damage you brakes more because of uneven wear sometimes a caliper gets locked up from extreme wear on pads past limit, he is actually saving you money in the long run. now as far as price it doesnt take much to change a caliper out, if you pinch off the line hooking directly to that caliper and unhook it along with the two bolts, all you have to do is put the new one in and pump the brakes back up and then bleed them to ensure all air is out of brake system, and depending on make and model, bleed them starting from furthest wheel from master cylinder....in other words you should be able to find a better price cheaper considering they want to replace the rotors instead of resurfacing them so that is alot less time to just replace them it is merily just parts changing, I hope i could help

Brake Vibration How to Change Brake Rotors on Toyota Corolla

My car vibrate at 100-120km/hr i have bought new tires and done the wheel balncing but it still vibrate and whenever i tried to apply the break at this speed it vibrate serously. it's a 2001 mazda mpv


This is due to poor settings of the wheel bearings,tyres,- check balancing once again, wheel drums/ brake pads,suspension , joints and steering.
In all the entire front suspension must be checked, the WHELL ALIGNMENT must be checked with precision and each of the wheels must be checked for damage on hub, axle or chassis.

I have a 1992 corolla brake peddal pulsalating?


if you can drive 50 mph and push on the brake pedal lightly and the steering wheel pulsates, the front rotors are warped. new does not mean straight, and cheap never means good. If you feel it in the pedal or your **** then the most likely problem is the rear brakes,.

When i use the brake, especially at high speds it makes a loud vibrating noise, the sterring wheel vibrates and shakes a little. this starting happening after i got al alignment and new tires put on. i...


The alignment would not affect your breaking as the alignment only controles the direction that the front wheels face. You may need to check your rotors and make sure they do not need replaced and check the breaks while you are at it. The pads should be evenly worn and the rotor should be evenly worn as well. There should be no deeps grooves in the rotor or break pads.

Shakes heavily when braking over 50 mph.


The shaking would be from your front rotors. First, loosen the lugs and retighten them with a torque wrench (not an impact gun) to the proper setting as described by Toyota. If the lugs are tightened unevenly or too tightly, it will artifically warp your rotors. If this does not fix the issue, your rotors are most likely warped from overheating, or being sprayed with water while hot, or from age. Get new rotors (and pads - always use new pads with new rotors), install them, and torque your wheels properly, and you should be in good shape.
