Thanks for the info- Exact part number I needed for the brake reservoir and clutch reservoir for my 2008 Superformance # 2787 for the Motive Power bleeder. I bought 3 quarts of dot 4 brake fluid. Clutch used probably less half a quart and brakes used probably 1.5 quarts and that was really letting a lots of clear new fluid flow out. A couple of observations. #1 with the location of the brake reservoir it’s important to make sure the line is not kinked. I originally placed the power bleeder on top of the air filter but that didn’t give enough slack in the line and it kinked right at the cap on the reservoir. I placed some towels on the engine bay and moved it right beside the brake reservoir and made sure the line is not kinked. #2 I needed Teflon tape where the 2 hoses connect or it would leak and not hold pressure. #3 the Willwood bleeder valves are different sizes front to rear. My catch bottle is a Gatorade bottle with a tube and another hole drilled into the cap to allow air to escape. 1/4 inch inside diameter tube for the rear (single bleeder for each caliper) . For the fronts there is 4 bleeders on each caliper. Per the Willwood website you only bleed the 2 bleeder valves on the top so I followed that. I used some old Rc boat cooling tube which has a smaller inside diameter for the smaller bleeder valves on the front. Followed the normal RR, LR, RF LF bleeding. #3 it seemed important for the tubes attached to the bleeder needed to come out going up before curving down to the Gatorade bottle. Any air in the system wanted to go up.
Car is new to me but has about 8k miles but I think the fluid is probably original to the car (13 years old). Brakes def feel nice and firm now and car was pulling a bit left on braking which is also gone now. Sorry for the long post but might help someone in the future
