Master Cylinder/Booster HELP!!
Hello fellow forum members,
I really hit a road block yesterday when it comes to my brakes and I need some help with what to do with my master cylinder/booster in my truck. I was getting ready to plum all my break lines and thought I would pull out the MC/Booster last night to bench bleed it before getting started. As some of you might know I purchased this truck from a guy who started the build but lost interest and I wanted to make sure I had the correct unit in the truck for my disc/disc setup. Here is the link to my build thread just in case along with pictures of my rear disc setup on the last page. http://67-72chevytrucks.com/vboard/s...d.php?t=723325 I finally got in all my break parts like copper/nickle break line & all my fittings organized to start the job. I also got in my flaring tool from eastwood tools & 2lb residual valves, 3 way splitters & frame clips so I was totally ready to start the job. The only part I havent figured out yet is what I was also going use for a proportioning valve. I was thinking about using this one from wilwood because it also has a built in brake switch. http://wilwood.com/MasterCylinders/M...emno=260-11179 Ok so here is the problem. The MC/Booster he put in the truck was for as far as I can tell for Disc/Drum setup. On the MC/Booster the only informaiton I can find is on the rubber plunger it says MBM and then on the bracket MBMPRAFMCT4754. ![]() ![]() ![]() So looking up MBMPRAFMCT4754 on the MBM site says that its the frame bracket but it also lists all the MC/Boosters being only disc/drum or drum/drum. http://mbmbrakes.com/search.php?Sear...MBMPRAFMCT4754 So what do I do now? Can I just replace the master cylinder and keep the booster? Should I call MBM and see what they say? Also I noticed when i tried to push in the rod on the booster it wouldnt move in/out. Is that because there is no vacuum or fluid in the booster? looking at the fluid bowls i believe the front one was larger then the rear if I recall correctly. Or I could just be freaking out over nothing and it has this MC on it but i would need to find a stamping of some sort or model number. http://mbmbrakes.com/mc2912h-gm-univ...er-1-1-8-bore/ Or scap it for a underhood booster/pedal assembly? Thank you for your help and time. |
