Hey i have a 2003 f150 supercrew with 150,000 when i back out of a parking spot and turn the wheel there is a pop when i turn the wheel and let off the break i dont really know what it is i checked all the bolt on the break and the caliper and every thing is tight so not sure what it is.

 

A pop from where? If it seems like its coming from the back, I would check your rear diff if you have a limited slip and add some friction modifier.

 

well i was in a hurry its more like when i hit the break and the pop is right under the breaak peddle

 

Any chance that it was just the ABS kicking in momentarily?

 

well not to sure wouldthe abs kick on for no reason

 

Everytime you start your truck (or any vehicle equipped with ABS) within the first 6-10 seconds the ABS module will run a diagnostic type test temporarily kicking on the ABS and quickly shutting it off and its normal. But idk about the popping. x2 on the limited slip diff. and friction modifier.

 

ok did not know that but heres what it dose i pull out of a parking spot cold start most of the time and put it in reverse then hit the brake theres a pop right under my foot as soon as i hit the the brake put it in gear and dose not do it till i cold start agin

 

Well I would say that the ABS is just running it's normal test.

 

ok thanks man i guess i never noticed it before thanks guys for the quick responses
