[Healeys] Front Drum Brake Back Plates

[David Nock]

BN1 backing plates the return springs go thru a hole in the plate and the BN2 plates have a peg for the return springs.

The wire wheel cars the center of the backing plate is flat on the front and back sides and rounded on the top and bottom.

The Disc wheel cars the center of the backing plate is recessed and round. Also the wheel cylinders are different and I think they use a 5/16 stud

This is just from memory. the BN1 plates will have 3/8" diameter holes where they fixes to the stub/swivel axle. Later ones are 7/16"

BN1 original part numbers are Girling GB40744-5 should you find any numbers. The last number denotes left or right ; I cannot remember which off hand.

I was of the opinion that BN2 and BN4/6 wire wheel were the same but I have checked and they do seem to carry different part numbers.

Only part of what you need in the way of information but this might help.

Best regards

  I have been asked if I can supply a Right Front Brake Back Plate for a 100/6 with wire wheels.

  I have several right side drum brake back plates but I cannot figure out which are BN1, which are BN2, which are 100/6 wire wheel and which are 100/6 disc wheel.

  The part numbers are as follows:

  BN1 ....7H4266

  BN2....17H4157

  BN4/6  wire wheel ....1B4496

  BN4-6  disc wheel.....1B4451

  I have looked in vain for a part number and although there are subtle differences in the pressings I'm at a loss as to which are for which car.

  Can anyone help?


  Thanks,
