My brother is chasing a brake fluid overheat problem during track sessions and the next step is to rebuild/replace the front calipers. Anyone know of a source for rebuild components or have a lightly used set of front base calipers they want to sell?
Background: Our cars are set up with identical brake components and mine never gets hot while his pedal goes to the floor after 15 minutes on the track. Good rotors, Raybestos ST-43 pads (1250F rating), Motul 600 fluid generously flushed and bled. GT3 brake ducts in place. His calipers are visually discolored from overheating. Next step is calipers and hoses.
