Prerunner shakes a lot when I apply breaks.. what for?

This is a new phenomenon with my truck..


Recently went on a long road trip and towards the end the truck and steering wheel started to shake a lot when i applied the breaks at 60+ mph speeds, but at slower city speeds the truck doesnt shake, before I left for my road trip I added new ceramic pads


Was wondering if this is because of warped rotors or bad steering wheel bushings

 

start off with brakes. Have them cut, and put in a new set of pads. You should be good to go. If not, have the rear drums cut also and adjust the rear shoes.

 

Did you have a panic stop? Sometimes it only takes one to warp em.

 

Yep sounds like your breaks might be warped.

 

What on my breaks are warped and what should I do about this?

 

Sounds like warped rotors.

Take your truck to a reputable tire shop and see if they turn/resurface rotors. Usually this is pretty inexpensive.

yes your rotors are warped and yes they need to be turned and possibly replaced. I hesitate to recommend ceramic as they are very hard and do not grab as well as the semi-metallic that come factory. This also tends to add to the overheated rotor issue.

 

A lot of good info to troubleshoot your problem. Hope its an easy and inexpensive fix.

 

warped rotors is the big thing with mine.... and i could have them re surfaced for $129(plus tax), or buy some performance rotors on ebay for $150(Free shipping coupon).....i chose brand new rotors, and 2 hours of my time to change them myself.

 

i had the exact same problems u have. my steering wheel shook like crazy when i hit the brakes. turns out i had extremely warped rotors and almost no brakes

 

WHAT???!!! i had my rotors resurfaced at a local machineshop and it cost me $12 per rotor and they were super smooth (smoother than stock)

 

Cold water on warm or hot brake rotors will warp them real fast and get the issue you speak of. Most people dont think about it when they drive their truck to the wash shop and they are all heated up. whats the first thing they do to the truck, put water on them... wala.

 

happened to me coming down I70 through the rockies in an overloaded Penske rental truck. Down shifting wanst cutting it so i had to ride the brakes, as little as possible doing the old trucker trick to stab for a few seconds and release to let them cool. In low gear you wouldnt gain speed as quick. But about halfway down those breaks were getting a workout, no vibes because i wouldnt let them get too hot. All of a sudden it started pouring rain and the next time i hit the brakes it shook so bad it was pretty much uncontrallable and almost ripped the wheel out of my hands. The vibrations caused the truck to sway and the car trailer i was towing started swaying like a biotch. If not for the CDL class B training i woulda been dead...

Sorry for the book, back to OP water on hot brakes=warpage
