After working on the front brakes, I still feel a brake pulsation when I brake. How do i fix it?
I have a Nissan Altima with 64k miles on it. I just got the original rotors that came with car resurfaced for the first time, and put in a new set of stock brake pads. I greased the shim surfaces and the caliper pins, made sure the tires were properly inflated, and used a torque wrench to torque the lug nuts to 80 ft-lb. Before I did this the brakes felt much worse. The steering wheel would shake when I hit the brakes, and I would feel a strong brake pulsation at the pedal. At least now the steering wheel doesn't shake! I feel a pulsation when I brake (not as strong as before), and am wondering how to fix it.

- Now get the rears turned.
- the rotors are not all the way true.they will need to be machined again if not replaced.could also be from the rear.drums out of round.
- is it the abs? not being bad but doing their job. the abs pumps the brakes and u can feel it in the brake pedal if it is working properly
- Remove the rotors and use a blunt end wire brush wheel that will fit a 3/8 electric drill.Thoroughly clean the inside of the brake rotors where they meet the lug nut hub surface. Clean the hub surface also to remove rust and corrosion. To check rotor side to side run out place a dial indicator with a magnetic base or clamp the indicator on the spindle to check the braking surface of the rotor run out. If you see over .003 run out the rotors should be resurfaced to true them back up.
- Try to aline yout wheels!!! toe and camber balance, the shaking comes couse, they are not aline, and make sure that your break pads and calliper are recedeu free dirt and harden grease, clean it up!!
- If it is not pulsating through the steering the remaining pulsation is probably from the rear brake rotors.
- you did,nt get any grease on the rotors, did you? take a can of brake cleaner and spray them off.
- Also check your wheel bearings, if they are worn they could cause vibration when braking.
