Re: Brake Pads
I have used since 2000 on my 2000 sil 4X4 5.3L truck the OEM pads until this year. I replaced the original rotors 4 with advanced auto lifetime warr parts including the lifetime pads. so far no problems.
I also had to replace the rear calipers 2 lifetime warr.what I found was the caliper pistons were sticking at a certain point when pushing back.this caused the pads to rapidly wear when they wore down to this area.
squeal is an easy fix. just coat the metal pad backing with an anti seize paste. this I have done for a very very long time and the brakes are quiet.
brake pads need in most cases filing on the metal backing plate ..this is due to the poor machining of the brake pad metal backing. the pads need to slide easy...also the caliper pistons need to be pushed back with ease. when I service the brakes I open the bleed screw THEN with a C clamp push the piston back. this then will reveal if they stick, also the bad fluid in the piston is discarded.
the caliper pins need lube and inspection for rust/binding replace if so. It may also need some filing if the pins fit too tightly into the caliper housing....
If you do this I'm sure you'll find the cause, and your braking will improve... with the pads sliding easy it will take less pedal pressure, and also the pads when not braking can slide back and not get hot from touching the rotors.
