Shudder while braking...new rotors, pads and tires...confused.

[maxse01]

Hey Guys,

I just put on new rotors, pads and tires. I also had the front wheel bearing greased and repacked. Before I would get vibration/shudder through the steering wheel and the whole car would stop inconsistently, like it does when the rotors are warped. I picked the car up last night and I no longer get anything in the steering wheel, but the whole car doesn't stop smoothly. It's glass smooth if I'm not on the brakes, so i'm sure it's not the tires. The car has 103k on it and I just bought it, full service history, no accidents.

What am I missing?

Thanks guys.

Chuck

Did you have brand new rotors installed or did the technician resurface the ones that were on the car? What kind of parts did the shop use if rotors were replaced? Did they do the front only or the rear as well?

Everything brand new OEM, front and rear.

Because I don't feel it in the wheel, I'm confused as to what it could be.

I guess it's possible you could have a bad one on the rear. Front pulsation usually causes steering to shake, rear pulsation kind of makes the entire car shudder. I guess it's possible there could be some kind of load on the slip yoke or u-joints under braking scenario causing it to not be smooth.

did you do a proper break-in of the pads? New pads can "cook" onto new rotors very easily if held in one place too long especially without break-in.

Are you families with uneven brake pad deposits? Search google if not...in a nut shell it will give u a warped feel due to sticky brake pad material left on one or more spots on the rotor. It happens a lot when a person gets new pads and breaks them in thinking they are doing things right. When the pads are nice and hot if the brake pedal is held down at a stoplight or such, it can leave a larger deposit of hot and sticky pad material. I learned the hard way. Hope that helps or may be able to rule this out on your cruiser.

You need to make sure the rear hub flanges are clean and true for the rotors. Any rust or deposits will make the rotors have runout. Pull the rotors and clean the flanges. Use a dial indicator to check for sure. Proper wheel torque is critical on the rears as the rotors float on the studs unlike the fronts. Were the rotors Genuine Toyota or a OEM copy ???
