Brakes 72 booster, master set w/p valve
I got this from a board member here and just wondering if anyone else has this set?
The part number is mbmbprct6772. I would like to look up the info on it and learn a little cause my knowledge of brakes is not very good... The proportioning valve is a pv2c also... Lost my pm's so I can't remember where this came from??? |

Re: Brakes 72 booster, master set w/p valve
You can find this complete kit at www.performanceonline.com
the pic you posted looks like a dual diaphram unit (7 or 9 inch). Don't think that's what any of these trucks came with. My '72 has a single 11" Delco Morraine Booster very similar to the unit described below, although the m/c and prop valve are different here as well. 1967-72 GMC Truck and Chevy Truck Power Brake Booster Kit 16667 View detailed images (1) 10% -------------------------------------------------------------------------------- SKUBB-11-6772T Weight25.00 lbs Market price$289.99Our price$259.99 Quantity Price *Note: Options Year of Vehicle Drum or disc brakes drum brakes (BBD-11-6772T) 2 wheel disc (BB2-11-6772T) (+$10.00) 4 wheel disc (BB4-11-6772T) (+$10.00) Proportioning Valve Bleeding Tool No Yes (PvBT) (+$7.99) Quantity 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 Need Help?Add to cart Our 1967-72 Chevy and GMC truck power brake booster kits will help your truck stop better than ever! These bolt on kits mount to the original master cylinder-power booster mounting studs found on the firewall, and use the factory pedal assembly. Exclusive bracket design is much stronger than OE brackets. Made of .188" thick 1018 mild steel minimizes flex in booster assembly and eliminates metal fatigue found on the OEM brackets. Available in 2 or 4 wheel disc applications and drum brake applications. Kit includes: • 11" single diaphragm power booster • POL improved mounting brackets • Master cylinder • Proportioning valve (disc applications only) • Prop valve bracket • Prop valve lines • Mounting hardware • Lifetime Warranty • FREE Vacuum Hose NOTE: Specify type of brakes when ordering. Product fits: 1967, 68, 69, 70, 71 and 72 Chevrolet and GMC pickup trucks. |

Re: Brakes 72 booster, master set w/p valve
I don't think your internals will be "wrong". As I understand it, these boosters all work the same way. The question for you will be do you want to stay with what you have and maybe have to work on some fitment issues? Your dual diaphram is deeper than a single but the bracket looks the same. So I think this will put your master cylinder farther forward. this may become an issue when trying to connect the brake lines that I think I see there. Those lines would go to the prop valve, and prop valve to m/c.
A kit like the one I posted solves all of these issues....or you could just look for another booster...POL sells those bythemselves too. YOu could also go with a rebuild by Cardone or something like that thru the major parts stores. It all depends on what you want to do, spend, or hassle with. |
