Brake shoes... I think? Help?

When I step on the brakes it shakes BAD! I have searched this forum and googled for hours and the answers seem to bounce all over the place.

The shake is felt in my seat, as I can let go of the steering wheel and no movement there what so ever.

Somebody recommended pulling the release for the E-brake while applying the E-brake... Which should test whether it is the front or rear. Did that, Ebrake slows truck with no shaking.

Stopping from faster speeds 50+ seems to have worse shake than from 30 mph?

Any suggestions... Please!!!!

Thanks,

Kp

Re: Brake shoes... I think? Help?

Have you stomped on the brakes recently? What kind of pads are you running? Ceramic pads aren't a good idea on a heavy duty truck as they have "material transfer" that when you step on the brakes hard or heat them up high enough, the material from the pad will actually melt onto the rotor causing a shaking problem similar to having warped rotors.

Re: Brake shoes... I think? Help?

Just got the truck in January, so I'm not really sure what type of pads are on there, but the strange thing is the fact there is no shaking in the front end or steering wheel, and the emergency brake does not produce any shaking at all.

Sure sounds like warped rotors. Does the brake pedal pulse when it is shaking?

That's the thing, if it were warped rotors, wouldn't I feel it in the steering wheel? I can let go of the wheel and jam on the brakes and it won't shake a bit, but I can definitely feel it in the seat.

Should I get my mind of it being the rear brakes?

I live about an hour from the nearest parts house, with 30 minutes to the nearest chain parts store. So I was hoping to get a couple ideas that I could buy on the way home...

Thanks

Rotor problems will not always be felt in the steering wheel. You will feel a pulse in the pedal and when the truck is almost stopped you may feel your body being 'thrown' forward and back, as if you were pushing and releasing the pedal.

brake issues that are felt in the wheel are usually caliper problems, brake line issues such as a collapsed line that runs from the frame to the wheel, or alignment issues that only show up under braking.

Rear brake issues that make you notice that there is a problem tend to be, low brake pedal caused by improperly adjusted rear brakes or a problem with the parking brake.

Re: Brake shoes... I think? Help?

Old and contaminated fluid can also make things appear rotors are warped. Brake fluid must be changed every 3 years

I agree on changing brake fluid but do not follow you on this old fluid making it appear that rotors are warped.
