Brake Caliper Repair Kit 38mm ATE
The old ATE Brake calipers can use all the help they can get for effective braking. We now offer this rebuild kit at a fraction of the cost from the original manufacturer. This kit consists of a new piston, piston seal and dust cover. 38mm fits models up to 1975 model year. Later models have a 40mm piston. If you are in doubt, you'll find that your caliper is stamped with a 38 or 40.
