include inspecting all the mechanical, hydraulic, and electrical components in either the back and front brakes. If necessary, replace the back and front brake cushions. Then, inspect or replace brake rotors or drives.
Some vehicle history originally. We’ll start off with calling the DIYer Earl. Jim was literally pulling his hair out. He needed to obtain his vehicle to pass the states emissions test in order to obtain a current Inspection Sticker. Akin to a friends “mini scan tool” and may have gotten the code p0171, left bank low fat. Meaning the left bank O2 sensor had “seen” a continuous lean condition and triggered a code to set in the PCM and turn on the Check Engine Delicate.
No challenege show up type of car you drive, don’t put out a brake repair. Replacing the rotors on any vehicle is a bit more costly that taking proper care of the pads and getting them replaced when necessary.
