I'm new to kart racing and acquired a trick olimpic Titleist chassis that had sat in the whether for a while. As a result, the brake caliper is sealed up. The bolts that hold the pad are completely stripped old so I can not rebuild. I'm not sure what caliper to order, or from where. The chassis id tag is 180079. I can find no markings on the caliper. I believe I need brakes. Any help would be helpful.
