Ok i put my jeep on stands and placed the car in drive. While the wheels are spinning i am applying brakes and the wheels won't won't stop turning. The drums are adjusted correctly. i am pretty sure the rear bakes are just not getting enough hydrualic pressure because i can stop the wheel from turning with the parking breaks. The entire system is bled correctly. My question is how do i know if its the master cylinder or the boost pump? Do i just have to replace one and see if it fixed the problem? Any input on this would be great. thanks
