Hydroboost / Master Cylinder Help...?
I have had trouble with both rear brakes sticking and over-heating. I am unsure the cause. Slides are good and pistons move freely. Either the common rubber line from the frame to the axle is collapsing or I have a different issue. One idea that was given to me is that my hydroboost and master cylinder are not compatible. I am unsure what hydroboost I have, I am pretty sure it is from a 6.0L (05-07). I picked it up from Ford but unsure the year model I bought one for. The hydroboost is stamped 729B. The master cylinder has 95 and is a 1 3/8 (which is the bore size). I am thinking I need a new master cylinder and want to be sure I get the right one. Can someone check to see what is stamped on their hydroboost so I can verify which one I have? Thank you in advance.
