Why has this Xterra always had a front nose dive when the brakes are applied? We have replaced the brakes several times over 4 years. The shocks are 2 year old Bilstein gas shocks. Are the rotors warped? Are the springs on the front too weak? Why do the brakes seem so touchy? It also seems a bit wobby on corners so do I need to get an anti-sway bar? Help. I want to sell this car unless I can figure it out.

will try to help.your front brakes and rotors may need replacement. when you apply brakes say,at 40 mph do you feel vibration on brake pedal or shaking in steering wheel? the vibration comes from worn or warped front brake rotors. while you have those rotors replaced,go ahead and have new front brakes applied also,or else you'll still have brake problems.always ask to see old parts when you have brakes and rotors unless you have a complety trustable mechanic! the rotors will be round and silver,a very bad brake rotor will have grooves cut in it.always shop for best price at different shops to get a picture of the price for replacement! do not be afraid to ask questions! front brake pads can cost anywhere fron $20.00 to $45.00 rotors can cost $40.00 to $50.00 each there will only be 2 rotors on the front and the brakes are complete for the front,both sides,on the front. as a general rule you'll replace your front brakes twice before you'll need to replace the back brakes because most of you stopping power comes from the front brakes. and as always,if you need further assistance please contact an expert!thank you for choosing fixya.com
the front rotors are warped ahd either need to be turned or replaced. use quality parts and motorcraft pads. if you use cheap rotors, they stand the chance of either being warped upon install or warping soon after.
it could be the brake pads have absorbed moisture and on the first apply they grab. I would replace the pads with a better quality and see what happens. The noise your hear under the hood is the ABS pump working because the wheels are locking up .
If your valve becomes defective then the brake pressure ratio to the front and the rear brakes will change. You will see or feel a difference. the front-end may nose dive or lock-up. The rear brakes may react the same way.
Appears you have a broken or sticking calliper. It is not releasing when you take your foot off the brake.
Remove the wheel in question, and check the springs. Lubricate with penetrating oil, and retry.
Your brake light switch is adjusted in all the way and is pressing on the brake pedal. This causes the brake to be slightly applied. As you drive the vehicle the brake fluid heats up and expands, the brakes will apply more and more until you see the smoke. Bottom line: your brakes are always applied at the master cylinder because something(usually the brake light switch) is out of adjustment.
drive the car apply slowly the emergency brake you gonna brake with the rear only if you fell the pulse its our rear drum that warp be carefull when applying the emergency try to hold the release handle at the same time if no pulse change our front rotor there nothing else that can pulse when you brake hope it help fixya our post thanks pierre
