Glad to see them available. Though, the rear half shouldn't have ribs around the perimeter.

Figures, the spare that I have been holding onto and paid top dollar for probably just dropped in value by half of what I paid!

OEM Bendix boosters were smooth around the base, not stepped like the repro units.

Agreed,...but not a bad looking repro though, time will tell how the fit/function is amongst buyers,...Wayne (RAMMAN) from Fort Wayne Texas has also introduced a line of Bendix boosters if anybody is looking?

Here's the HEMI and the B body Bendix for comparison to the above post

Wayne is selling the same boosters. I also sold a couple lately.

The mounting studs are metric and you must enlarge the hole in the original firewall stiffening plate a tad. Everything else looks pretty good.

Wait, so Wayne (Ramman) is selling / making the ones that he makes with the step on the back part? I thought he was only rebuilding them and making specific parts, not the whole thing?

That's the way I roll, too. Buy 'em high, sell 'em low.

I knew something didn't look quite right. I went through every booster in NAPA's warehouse to find the correct one, and they ended up rebuilding my original for me.
Hard to find.

These are the only new, reproduction Bendix style boosters available. They are not available for Hemi applications.

The Bendix is what will clear the valve covers/hood up on the bracket, Midland/Ross has a bigger diameter .

Isn't the Bendix a dual diaphragm to make up for the small size?

Re: Reproduction 68 -70 B-body , bendix boosters !!!! - 02/11/13 11:38 PM

JohnRR,you'r right on, had a hemi RR with power drum brakes, had the Bendix booster and drum master and dent in the air grabber box!

The Midland-Ross booster is a single diaphragm booster meant for drum brakes. The Bendix booster is a dual diaphragm booster meant for the disc brake master cyl. Granted, the Bendix is a smaller diameter than the Midland-Ross so that could be why it has to have a dual diaphragm.

I recently parted a nice clean all original 1969 Sat wagon that had 4 wheel drum brakes, and a dual diaphram Bendix booster....

Dayclona is right. I forgot about the wagon drum brake application. I wonder if it gives more stopping force or less pedal effort for stopping force due to the dual diaphragms?

Granted, I havent driven a car like mine with the midland ross booster, but my 69 charger that has the bendix disc brakes if you hit the pedal too hard, you'll end up going through the windshield! LOVE, LOVE, LOVE my brakes! Wish the ones in my 07 F150 were this good!

Re: Reproduction 68 -70 B-body , bendix boosters !!!! - 02/15/13 03:59 PM

wonder if the midland & ross requires more vacuum to opperate as opposed to the bendix ? just throwing a few ideas out there !! like i mentioned bendix on hemi but wedge motored 68 -70 b bodies midland & ross !!
& bendix on a hemi car , thinking giving better stopping power with less vacuum being generated with a hemi motor due to cam , maybe

never seen a roadrunner or charger with a wedge & powr drums with a bendix booster !! wonder why
just some thoughts guys ,
thanks again for all your imput & feed back

I've run the Midlands and Bendix boosters on wedge and HEMI cars with "big" (large dur.) cams, really doesn't matter as to the booster used, ...vacumm supply is key, generally 10" of vac minimum is fine for a manual car, as the engine recovers vacumm for the booster when you clutch to engage the brakes at low speed operation, the same engine set up with an automatic generally cannot substain repeated braking at low speed operation, which usually requires the need for a reserve canister in the system, or in worst cases, a vacumm pump

more good infomation !! the 440 in my satalitte with current cam idles in gear with foot on brake at 10hgs of vacume
thinking of buying this booster to fit with none power drums
seems a better deal sourcing the midland & ross booster , master cyliner / fire wall plate & pedel bell crank linkage !!

thanks again !! for all the feed back !! given me some things to think about
