inspecting brakes Posted by JimBlake [Email] ![]() ![]() ![]() In Reply to: ? about this subject -longish, Alexandros, Wed, 12 Mar 2003 10:09:25 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Jack up the car, take off the wheel. The brake caliper squeezes the rotor, but its the pads that actually touch the rotor. One pad outside & one pad inside the rotor, for each wheel. Each pad is a steel plate with maybe 10mm or 12mm thick friction material that actually touches the rotor. The friction material wears down to nothing, you have to change them before the steel backing plate grinds into the rotor. Probably 1 or 2 mm is the minimum.
You can see the outboard ones thru the spokes of the wheel, but you take off the wheel to see the inboard ones. "Usually" the inboard & outboard wear out together, but if they don't its a sign that something else is wrong.
While you're in there looking around, its a good excuse to inspect the brake hoses, too. They should last much longer than 4 years, but they're right there so check them out.
Ever have your brake fluid changed? Do it every 2 years. Brake fluid absorbs moisture from the air & gets corrosive. Also lowers its boiling point. Air in the brakes & old fluid might contribute to soft brakes...
