this aint about el caminos but my dad has a 2002 chevy z-71 1500...he was wonderin if since it has antilock brakees do u need to changes alll the pads at the same time or will it matter??? thanks

It is not required but I have never seen a good reason not to change them in pairs---like fronts or rears----the antilocks do not require it however..................Dan

8) 70% of your braking is performed by the front brakes, so you can expect your front brakes to ware quicker then the rears. With that said I personally end up changing 2 front pair to on set of rears. To the unsuspecting person the marketing ploy is the companies that do brake jobs want to do what they call a 4 wheel reline this is bogus as far as I am conserned. :cool:

Agreed, when I worked at Goodyear, we were required to take measurements of all the pads/shoes and record them on the work order. Recommendations were then made on the measurements. This would be a good practice for any reputible shop. Not only does it help sale "required" brakes jobs, it also acts as a diagnostic aid in determining if one of the calipers is sticking and in need of a rebuild..

Well since this thread started out as non-Elky... I'll make it even more non-Elky :-)

The front to rear wear rates will vary by vehicle and usage. While it is generally true that the front wears much faster than the back, it is by no means universal. Case in point: recent Ford Mustangs have traction control. This detects rear wheel spin and prevents it by, among other things, applying the rear brake on the spinning wheel. Needless to say this does "consume" brake pads on the right rear at a bit faster rate than the typical norm :cool:

This general feature is becoming more common as we see more rear wheel drive vehicles being manufactured again.
