[Healeys] Rear brake adjustment

Sat Apr 3 03:52:33 MDT 2021

Mine is called “The Old Banger”. Not always and only by me. 

Don’t know if the expression “old banger” has made it off these shores. It infers a slightly disreputable old car, usually on its last legs. Often to be found on a dodgy garage forecourt, mutton sold as lamb.

To be fair, I’m not quite sure how I’ve got into the habit of calling it that. The car is nothing special, but the name is not fair.

Great idea, Roger! I bought an alignment kit with a similar inclinometer.

Bob - just for interest.

Your large caliper (that I don't have)  idea got me thinking and remembering that I have one of those digital inclinometer angle boxes that I use to set up my saw.

The spec. claims 0.1 deg accuracy and it is spot on when comparing to an engineering square.

So I used this as shown in the photos to set the shoe at 90 deg to the hub (not backplate)

The 0.1 deg error translates into 4 thou at the edge of the 2.25 in width shoe.

I think centering the shoes with the brakes applied works well, but only with new/freshly turned drums and shoes. If the shoes aren't centered they will wear uneven, and lock up uneven.

The best idea I've come up with is to use a large caliper--not easy/cheap to find--and make sure the shoes are square to each other. If they are, they should be orthogonal to the backplate.

Obviously the quality of the felt being used is not satisfactory.  I've got a pair of BN1 rear brakes here that still have the felts in place and are still greasy.  

I don't believe eliminating metat to metal is the intent ... just to provide sufficient lubrication to eliminate squeaks.

Bob,

Yes agree about the felt bushes. I assume that their only function is to prevent metal to metal contact ?

So do the fibre tubes protrude slightly beyond the end of the pegs ?

Will try to locate something suitable.

Wonder how you adjust these pegs ?

There seems to be 3 different techniques:

The Moss method with chalk marks on the shoes. 

The Salter method by adjusting in/out to each shoe edge then setting to the mid point.

The usual  method - centering  the shoes (by stomping on the brakes) then adjusting the peg to just make contact while shoes are clamped.

I tend to favour the last method .... ?
