How do you measure rear drum brakes?
As far as measuring, the most accurate way is with the drum/hub removed from the axle. Measure across the diameter of the inside of the drum and the depth of the swept surface of the drum.
Can you replace drum brake shoes?
It’s not uncommon for brake shoes to last twice as long, though. If you drive carefully and keep up on maintenance, the brake drums should survive at least two sets of brake shoes before requiring replacement; in some cases, the drums will need to be machined but not replaced.
How thick should drum brake shoes be?
Separate drum brake Shoes with bonded lining should, for safety, be replaced when the lining is worn to & 1/10 in. (3 mm) thick, even if a minimum thickness of 1/16 in. (1.5 mm) is quoted in the car handbook.
How do I know what size brake shoes to buy?
Measure each by placing the flat base of the tire tread depth gauge onto the brake lining and then pushing down on the sliding ruler. Compare the measurements of each rivet in 1/32 inches to determine even or uneven brake shoe wear. For bonded shoe measurements, use a brake lining gauge.
How many brake shoes did the early drum brake system consist of?
Each brake assembly has two shoes, a primary and secondary. The primary shoe is located toward the front of the vehicle and has the lining positioned differently from the secondary shoe. Quite often, the two shoes are interchangeable, so close inspection for any variation is important.
How much does it cost to replace brake shoes?
The average cost to replace brake shoes is between $199 – $275. Price generally varies based on the type of car you have the type of auto-shop you go to.
What is the minimum thickness required for legal brake shoes?

How thin can brake shoes get?
Brake Pads Appear To Be Thin. For the braking system on your automobile to function properly, the brake pads should not be allowed to get thinner than ¼ inch.
How do you measure brake drums?
Cut one piece at the maximum diameter 422 millimeters and cut another piece at the halfway worn point which would be 420.5 millimeters. Now by placing these inside the drum- straight not at an angle you can quickly tell approximately how worn your drum is. Be sure to check for out-of-round and bell-shaped drum.
