i just got done putting on new brakes all the way around i had a abs light shuddering problem. i got the abs light fixed not from the brakes though. but the truck still shudders when im braking. it dosen't seem that bad but its still there. i got everything turned so nothing is warp but i dont know what else it could be. seems like it is coming from the front but i dont know for sure. could it be something in the front suspension. or the bearings in the hubs?
its a 1995 2500 automatic if that helps
It vibrated before with the old brakes and does it now after they have been turned? Easy, time for new rotors. When rotors warp, usually from incorrect torque hen applied heat, you can cut them flat, but the they will warp back to thier previous position or even worse. Usually, this happens as soon as they are applied and heat is generated.
While it will not hurt to check everything in the front end. That may not be the cause. My first hunch is the rotors.
It is also possible, although unlikely, that alignment can be the issue. But if it is that bad, toy would most likely notice it all the time.
I would jack up the front end, pull the tires, and check for run out. You do not need an expensive dial indicator for this. You can use a piece of coat hanger pinched under a bolt. be to be very near the surface of the rotor. And give it a turn. If you position the wire to the outer edge, it will be easier to see any run out. And you can use a dime, penny, nickel to measure the run out. Primitive, but it works.
Take your properly sized change to the parts counter and have them mic it. If the rotors are out of spec. replace them. Otherwise, you are beating yourself up!
I really like gas slotted rotors, as I have seen a few cross drilled units crack.
