use a pad wear indicator :)
If you are checking for brake wear then you would need to know the amount of travel to measure distance between the components.
Brake pads have a wear indicator to let you know when they need replacing. The screeching means you need to replace the brake pads, and the sooner the better to avoid damaging your rotors (the shiny disks that the brake pads rub against to slow your car down).
You either have a bad brake caliper or the brake hose is bad.
One possible reason is that the brake linings are worn to the point that they need to be replaced. This is meant to be an early indicator of brake wear.
plumbers wear boots and overalls when working at they wear boots with steel caps in them so the dont brake there toes if they drop something on it.
ONLY if you PAID them to replace the brake pads and nothing else caused the quick wear of the pads.
normal wear and tear. Brake light switch, bulbs or sockets.
First I would have the rear rotors removed to inspect the emergency brake shoe's and rotor for wear. Sometimes people are known to drive with the emergency brake engaged which will wear the shoe and rotor. If they are still within specs, there is an adjustment on the shoe's
To allow the engine to slow the vehicle rather than put wear on the hydraulic brakes.
Brake fluid contaminated with moisture and dirt along with wear would do it.
Brake rotors wear because during use, brake pads are pushed against them while the rotors are turning. It's the friction between the moving part and the staationary part that slows the vehicle down. Pads wear too, usually quicker. Brake rotors wear due to use, they are considered a service item.
