The conversion seems pretty straight forward, but I am wondering about how easy or difficult it actually is. The manual brakes are OK, but I am spoiled by years of power assist.

Power assist on the MGB is NOT going to increase your braking efficiancy.

It eases pedal effort only.

Put your dollar$$$ elsewhere on the car.

See you in Wheaton on the 26th of this month for the Swap Meet.

You would be better off working on beefing up your leg muscles. ;)

@Rick, I understand that, and once I rebuild the fronts later this month I may decide that they are fine as is. I was just interested in the experiences of others. Heck, until recently I didn't even know that power assist and an automatic were ever even available on the B. I would never want a slushbox in my B, but the power brakes might be worth while. And yes, I will be at the meet. It has been on my calendar since the day I bought the car.

@Terry: well, fortunately I'm a cyclist, so I have pretty good quads. LOL

Drive another member's MGB that has servo-assist brakes, then decide.

I have an automatic in my 1969 MGC...it makes for a GREAT road car. In the MGB, it would probably warrant the moniker "slushbox".

I had a roommate in college (Ferris in Michigan) who had a 1972 MGB/GT with an automatic transmission (BW35, same as in my MGC).

The first 6 months that I had my 'B', the booster didn't work at all. the car still stopped well and normally. After I replaced the booster there is less pedal pressure required, but if I had a non-booster car, I wouldn't add one.

Mo, the extra torque from the 6 in your C probably helps a lot. I don't have anything against automatics in general, my last 6 vehicles have had them. But in a low power situation like the B an old fashioned 3 speed auto would just suck out some of the fun.

Less pedal pressure required.....but no increase in braking efficiency.

I think that's what I was implying.

BTW...I drove my MGC for two years without servos. No problems whatsoever.

Agreed.

Rick, so you did. I didn't read carefully enough.

I had a GT in the late 80's after college and my dad had a '63 Spitfire and a '69 MGB, so I have plenty of experience with non-assist. So I was curious who might have added it and how they liked it.

Interesting. Look for the recent threads where RB owners are trying to ditch their "power" brakes.

My booster might not be working but it doesn't seem like much of a difference than without one. I don't think there is a lot of boost pressure in an MGB. Maybe i would feel it more if the car had an automatic transmission.

FWIW - a boosted car with a broken boost would be worse than an originally non-boosted car, as the pedal leverage (i.e. distance of pedal to fulcrum point) is greater with the non-boosted cars than the boosted cars. This is the major reason converting between the two requires changing out the entire pedal box and pedals.
