Looking For Corrosion And Wear On Your Brake Pads And Discs.

Check how much meat you have on the outer brake pad....

....and the inner pad, minimum thickness is 1.5mm
See that the wear indicator wire is still intact.

Check if there's an outside lip developing on the front face of the brake disc (this disc has), pitting....

...and build up of corrosion/rust on the back.

On the edge of a new brake disc there should be the minimum thickness stamped, this one is 20.2mm
