SOME BRAKE HISTORY
by Lorne Goldman

BRAKES PRE-1993

Most part numbers for earlier Morgan brakes can be found in the GoMoG Workshop Manual Parts Section. After 1978, the tale is easy to tell. All cars used a Girling 3/4 bore Master Cylinder powering 2 pot calipers and Triumph rear shoes through Girling wheel cylinders.

The wheel cylinders can still be sourced from Past Parts. However, as these cylinders have always been a relatively quick wear part, it is wiser to keep the old ones and have them resleeved in stainless steel and refurbished. See the GoMoG Parts and Services pages (under BRAKES) for companies that do this. The other parts are not difficult to source.

One exception, the Master Cylinder. These are no longer made and were VERY expensive when they were. They can be resleeved and refurbished. However, we have found that there is a fine replacement in another 3/4 bore MC made by Subaru for their 1979-1981 Brats.

The lines must be curled and adapters purchased but this makes a fine replacement OR a very wise retro-fit for the earlier single line Master Cylinders
cars.
 
 

BRAKES POST-1993

In June 1993, the Factory moved from the brake system above to a servo-assisted Master Cylinder (servo and MC are sold as one unit) powering 4 pot calipers in front and self-adjusting shoes and wheel cylinders at the rear. These are made by AP Racing, a UK brake supplier/manufacturer.

As of this date, the hydaulic parts are still available through the Morgan Motor Company. The calipers have been discontinued (see below). The rear wheel cylinders last far longer than the previous gneration's. The hydraulics (MC and servo) can be refurbished.

BRAKES POST-2008

In 2008,  the Morgan Motor Company moved to new brake calipers, also supplied by AP Racing.


 

AFTERMARKET

There are also some excellent aftermarket sources serving the Morgan trad community for calipers and rear disck brakes. See Brakes
