Hi Mick,

Could the brake pressures on opposite wheels be checked and the adjustment corrected until they are equal ?

If unequal wheel diameters are suspected, can the diameters be checked during servicing so that the larger diameter wheel can have another day’s use with the abrasive brake blocks ?

Gday Richard, All

The problem with using abrasive brake blocks to get rid of flats is that
the brake pressure on each wheel is rarely the same and therefore unequall
wheel dia will result on the same axle

Cheers, Mick

South Melbourne depot around 1990 got a batch of 'Ferrodo' brake shoes with a layer of carborundum glued to the face of the shoes.

The experiment can't have been a success because no more were seen.

Nevertheless those composition brake should would very slowly grind away minor flats, but not during just one shift.
