hi guys I'm not to sure what to do my car has been acting up the last few days and no light on dash to indicate anything so yesterday i was driving notice it was hard to acceleration to even 30m/h and the car started to shake like crazy. so i take it to the nearest shop jake up the car and the mechanic try to turn the tire wouldn't rotate and all and all 4 wouldn't and said it has do with your abs cant help you take it to Lexus and Lexus is booked until June lol.
so after leaving the shop and driving home the symptoms wasn't there but i have to press the brake pedal all the way down for some braking action. so i take the car for a spin around the block cant acceleration and a foul smell coming from the brakes. so my question is anything i can do to rule out of few things and do i have to take it to Lexus any help will be appreciated

 

pop the hood and on the driver side there is a small relay box that has the abs and trac relays. pull the abs relays. that way the whole system is bypassed. i had the same problem as you had and i pulled the abs relays. this solved my problem. the abs motor is too much and i know how to drive so i never bothered to replace it. i have been driving without abs for over a year...even in the winter and it has worked out well.

most likely its the abs motor but it may also be the brake booster. most likely the abs motor though.
