BRAKES

[pspeaks]

I have never driven a MG with power brakes and was wondering if the difference is significant for a car that weights what a MG does.  Is it nothing more than changing the pedal assembly mount box and adding the accumulator and vacuum hoses, or is there more to it than that?  I don't plan on doing it right now, but when I get the body work done and the new paint job, I'll need something to do on a Saturday afternoon :-)

Paul,

I went the other way and converted my 78 to the dual circuit 68-74 system. Boosted brakes were easy, too easy for my taste. Hole where the pedals drop thru is slightly different shape on boosted cars.

Geoff,
I am at that exact point on my 78.  Hate to reuse the old booster and was thinking going retro back to dual line.   Did you by an old dual line master or just use the 78 w/o the booster?

Gary - I have a '76.  Changed it to the early chrome bumper pedal box & used the dual circuit master from those earlier cars.  I like the feel of the brakes better w/o the booster and I think the curved cover looks better under the hood.  As Geoff notes, the shape of the opening on the firewall is different so you have to do a little modification there.  Not too hard though.  If you swap them out, make sure you get the pedals as the pivot point (distance from where they connect to the brake & clutch push rods to where they pivot on the bolt they hang on) is a different length -- forget the ratio, but they are different between non-booster & booster pedals.

I used the original 72 dual line master cylinder which I rebuilt because the car had been setting for some time before I started the conversion.  I also replaced the calipers and all brake lines as well as the rear from the backing plates out.  At my stage of life my driving habits aren't all that aggressive any more so the stock brake system seems to be adequate.  I was giving second thoughts to a brake booster for creature comforts but I need to concentrate on other up grades this winter so I think I'll just stick with what I have for now.
