the original mastercyl. turned out to be shot on the RX. it was leaking and had poor pedal feel. I ordered a new master cyl. identical to the old one. installed and bled the brakes gravity style. Now the brakes work but are draging bad like its not relaesing the pressure. I suspect the hill holder is at fault.

any one else have this happen? I think it might have been happening a little bit before I installed the new master cyl. but now its bad.

I have not expierenced it, but it makes logical sense, I would loosen the hill holder adjustment and see what happens; if your last MC had issues, it is likely that the HH wasn't adjusted properly

Either the hill holder, or the pushrod adjustment. I haven't actually pulled the master cylinder off my Subaru to see, but if it's the same as pretty much every other car on the planet, there's an adjustable pushrod on the end of the master cylinder. If the brakes are dragging, you need to screw it down a bit so it's not sticking out as far.

Here's annother posibility ... has it sat for any length of time? If it has sat for over 6mon. or more, it's also possible that the brake calipers themselves are dirty, and the actual cylinders that are on the calipers can sometimes stick. To check this make sure you use ONLY and I do mean ONLY the same brake fluid that you put in the master cylinder to clean them. Have you had the Calipers appart at all? I saw this problem on motorcycles many times, but then again they tend to sit out the winter months and sometimes the rubber seals just get hard and less flexible, causing them to stick.
