We have a 1999 4.6 4x4 f150. It has a very strange braking issue. When I slow down the truck, the pedal moves up and down and the truck shakes a little. At speeds of 15 mph and below, it drives and stops normally. It is so bad that we have to coast to a stop. The abs light is on at times and has been for years. The braking vibrations just started three months ago.

The left front bearing may be slightly bad. I don't need it all perfect but just so that way it is usable and drivable. This is my first time posting here your help would be greatly appreciated! In alaska, our mechanics charge $100+ an hour!

 

Welcome To FTE!!

It might be the wheel bearing....or... it could be warped brake rotor.

 

Welcome!!
As enriched said most likely warped rotors specially if you been city driving and go thru puddles creeks etc they are most likely going to warp. At rare times a bearing causes vibrations too.

 

Thank you so much for all of your information! Does this look like a good rotor kit? I'm new to all of this!: https://www.amazon.com/gp/aw/d/B00E1SLYPW/ref=mp_s_a_1_12?ie=UTF8&qid=1498417922&sr=1-12&pi=AC_SX236_SY340_FMwebp_QL65&vehicle=1999-54-666-------------0

 

You can have yours resurfaced, that's if they are still within specs.
