Chrysler Master Cyl

#1 Post by John_Heard » Mon Apr 07, 2008 6:13 am

I'm making some changes to my brake system and looking at using the Chrysler / Dodge master cyl like all the race car shops sell. I read a post somewhere that a 1981 Dodge Ram D-150 with manual brakes has a 1-1/8 bore which is what Aerospace recommends for their 4 wheel discs.

Problem is going to the parts store the new and rebuilt ones are Cast Iron. Does anyone know what parts stores / manufacturers sells these in Aluminum now?

Was the NAPA one a aluminum body? By any chance do you guys remember the name brand that was on the Master Cyl Box / Manufacturer?

Did any of you guys have problems finding a fitting to work in the rear 1/2" outlet? I've been having an issue finding a fitting that has enough thread to seat on the internal flare before running out of thread. I've looked at most of the parts store's here and no luck, about ready to chamfer the 1/2 port some so the fitting will sit down deeper and seat.
