Brake Pulsings issue

Hello. When i apply pressure to my brake over 15mph they pulse really bad. the whole truck shakes. so i replaced my rotors thinking that would sovle it. but nope, the pulsing is still there... what do you guys think it could be? i thought the pads looked alright when i changed the rotors.

 

sounds kinda odd to me. it could sure enough be the pads, depending on how many miles you have on them. they may look ok, but they could be uneven or something. also, you may want to check and regrease your wheel bearings....just a thought.


what kind of rotors did you get?? ive seen new rotors that were defective, so this may be the case with yours. hope this helps!!

 

Check and see if you have ABS brakes. If so have them checked to be sure they're working properly. ABS brakes will pulse if the brakes are applied hard, but you shouldn't feel a pronounced pulse during normal braking.

 

Check your calipers. I know my toyota had those problems and it was corrosion on the slider on the calipers. It was pushing on one side of the rotor instead of squeezing.

 

When you change rotors, you should always change the pads.

If a rotor is warped, the pads themselves can get 'wear' patterns in them.

I would take the rotors off and have them checked and/or turned again if needed. Get yourself some new pads.

Check the calipers to make sure they're moving freely. Like Phisherman said, there's a slide that needs to be cleaned & lubricated.

Good Luck!

 

also tourqe your lugs evenly or you will re warp the rotors again.

 

I occasionally have to re cut a drum but rotors are usually better. They don't make a noticeable spiral pattern do they? If you dragged your finger over them it shouldn't drag your finger in. That can pull your brake pad like a screw and pop out when it can't possibly go any further. Check slides and throw some grease in there. Probably recheck everything again.

 

Never mind about the cutting of the rotor, that problem doesn't just start happening. It's late, probably should go to bed.

 

wheels out of balance? Sure its a pulsing, not a shaking?

Did you have the drums checked? Dunno if they can cause a pulsing, but its something to look at.

Look into the rear u joints, if there bad they can make a vibration like no other.

funny thing, is mine does it occasionally also. Not quite sure what it is thou. Im goign to grease everything and see what happens. I have my summer wheels I gotta change out, and see if that helps either, since the winter tires are shot.

 

Could be rear drums and shoes. Is there a shake it the steer wheel?
