Should brake pads be in contact with rotor?
Share with them that optimal braking calls for solid contact between the brake pad and rotor and that the best way for this to happen is with new rotors. New brake pads and new rotors ensure that both will wear evenly, avoiding premature wear that can lead to the brake pads being replaced sooner than expected.
yes, there will be clearance about 2.5 mm in cars and 1 mm in bikes.
Yes they stay in touch with the disk friction surface all the time, unnmoving. The only difference is whether there is a piston pressure or not, depending on whether the brakes are applied. The only pad movement is when it is being worn.
To maximize braking performance, all brake pads and rotors must be "bedded-in." Bedding in, breaking in, or burnishing - are all terms for conditioning new disc brake pads and rotors.
If you do not properly bed your rotors, your vehicle will not deliver optimal braking performance. Braking systems that are not broken in will have random, uneven deposits of brake pad material on the rotors.
- Speed up to 35 mph.
- Use moderate brake pressure to slow down to 5 mph. ...
- Repeat 2-3 times.
- Speed up to 55 mph.
- Use strong brake pressure to slow down to 5 mph. ...
- Repeat 4-5 times.
- Drive for 5-10 minutes to allow the brakes to slowly cool down. ...
- Park the vehicle and let the brakes cool for an hour.
For up to the first 200 miles, every time the brake pads make contact with the discs, it increases the contact surface area between the two, which leads to better braking in the long-term. So you should remind your customers to brake lightly, but brake often, for the first 200 miles after new pads have been fitted.
Improperly installing new brake pads or putting your brake parts back together incorrectly could compromise the safety of you and your passengers. Being familiar with the parts and repair process is critical to avoiding small mistakes, like a slightly loose caliper fastener that might affect braking performance.

As a rule of thumb, brake pads should be replaced about every 50,000 miles.
How much space should be between brake pads and rims?
You should have an ample amount of free play at the brake lever, and the brake pads should be about three-millimeters (1/8-inch) away from the rim.
Driving too long on worn brake pads can cause rotor damage. As the brake pad wears down, the metal becomes exposed leading to metal-on-metal contact when you apply the brakes. This harmful contact between the pad and rotor can cause deep grooves to develop in the rotor.
