In the process of switching to power disc brakes, thankx to all those who contributed to the existing discussions, big help. I'm looking for a smaller alternative to the OEM P/B master cylinder. With all the small cars out there these days, I'm hoping someone has figured out how to adapt a small M/C setup to avoid the HUGE OEM unit and the monstrosity shock tower brace that accompanies it. My manual drums work pretty good, but the shoes keep cracking, damn kid drives too fast (not me) Can I switch to disc brakes and stay with the manual M/C? Front is a given, but how about all 4 wheels? Pros/cons, or no way? I've considered a hole in the floor Fred Flintstone style, but I keep going thru sneakers
On my last mav I used a 7 inch booster from ebay, with a granada M/C. It all cleared the tower braces and shock tower just fine. My latest mav has a 7 inch booster with a 89 Ranger M/C and it clears everything great and looks super cool. havent driven the car and wont for some time, but I am sure it will work super. I am also certain that the 8 inch booster from ebay will fit also. I am running the single diaphram unit as I dont think there is room for the double diaphram unit. There are some pics in my galleryhttp://mmb.maverick.to/attachment.php?attachmentid=63874&stc=1&d=1394042193
I think there is a Geo that has a real small booster which is a popular swap. The only downfall I believe is the Geo master only has one reservoir. I think this setup is most popular with the falcon crowd.
Like this one? http://www.ebay.com/itm/7-STREET-ROD-HOT-ROD-POWER-BRAKE-BOOSTER-FORD-CHEVY-/140943862505?pt=Vintage_Car_Truck_Parts_Accessories&hash=item20d0e8aae9&vxp=mtr That's a pretty cheap upgrade! I like it!
What I have learned is the OEM Maverick power brake booster and M/C mount on the firewall in pretty much the same place as the manual M/C (once you make the 4 new holes), but the rod that connects the pedal is offset to the driver's side significantly, as a result the stock manual brake pedal doesn't work if you are installing an OEM setup, you have to get a pedal from a donor P/B car. If this setup as 55 is suggesting has a centered rod going through the firewall, it can be assumed because the OEM manula M/C has a centered rod, the OEM manual brake pedal will work, you just have to fabricate a connecting rod from the booster to the pedal. Does that sound right? Am I missing anything?
looking into this as I hate the xcross brace,,did you make the pushround or buy an adjustable one,,i like using the stock drum brake pedal setup then adding the 7 brake booster, keeps everthing looking nice and tight,,the m/c needs to be changed to disk and everything else but as a whole would look much better
Here is the pushrod I made........... I cut the stock one then welded it to a threaded nut(from ACE)it is now adjustable. In the bottom pic, you can see the location of the lower nuts of the booster.
