I have a 2004 rx8. I have recently replace all caliper, brake pads, rotors, and the master cylinder. Now the rear brakes are not getting hardly any pressure. Has anyone else had issues with this? any and all advice would be greatly appreciated!

 

Possible you have air in the system?

 

Are the front brakes letting out the proper fluid when bleeding? Did you bench bleed the new master cylinder before installing it?

 

99% of the time, it is a bleeding issue. When it happens to me, I usually hit the easy button and pay the dealer $90 to flush it for me. That always fixes it.

 

yes we did bench bleed the master cylinder

 

Are you bleeding the brakes form the RR, LR, RF, LF?
