I have stock front disc brakes and Wilwood rear drag disc brakes. Should I get the MP 1 1/32 or 1 1/8 bore master cylinder? Other suggestions for a new brake master cylinder? It depends on the pedal throw and firmness you desire. A 1 1/8" bore truck master is very firm and a short throw but I prefer that. 15/16 rwd car master is preferred by quite a few people. O'Reillys sells the aluminum MC's for $26.

Should I get the MP 1 1/32 or 1 1/8 bore master cylinder? Sometimes you don't have a choice; if the combination of calipers and the pedal ratio require more fluid volume, you'll have to sacrifice line pressure and go with the larger diameter MC or live with a low pedal.

I have the same basic setup on my Savoy and I have used the 1 1/8 bore master from Wagner and then tried the 7/8 bore Strange unit and the pedal feel wasn't that drastic. Both performed well but the Strange unit had a more aggressive stop than the Wagner unit. Both of them felt confident but the Wagner was "smoother" I think the Wagner was an 85 Dodge Diplomat application. I use them without any prop valve just a distribution block and the car stops perfectly from 125 MPH. Gus

I had the same set up in my Cuda since 1988 I used the stock master and factory plumbing. The only thing I did was pull the residual valve out of the master cylinder. It was simple process. Inserted a small screw into the brake line(rear brakes) seat cone in the master, wiggled it out and the residual valve popped out. Inserted the seat cone then the line and blead the system. It has a great pedal The car was not super fast ran 10 teens at 130.
Ok

I forgot to mention I currently have a master cylinder from a drum front and rear in the car now. I will probably try the 1 1/8 from Napa. Thanks for the link to the part numbers. Cudatom, I had recently seen that trick but was planning to replace my master cylinder which is leaking like crazy.
