how do you know when to change brake pads and rotors and what are the best brake pads and rotors to use
The best test for when to replace the disc brake pads and brake shoes (friction material) is to remove the wheels to inspect the brakes. The friction material should not be worn away; causing metal-to-metal contact - in fact the brake material may be down to about 1/8" or 1/4" thickness. This would be time to replace the brake pads and / or brake shoes with new. Try the 'How-To-Guides' feature this website - for specific steps to inspect the brakes - including photos.
