| fully dimensioned drawings or sketches of the master cylinder operating lever, also the lengths of all levers to rear brakes from servo & pedal. I will make a recommendation. The master cylinder is 1 1/4" dia is it not? The dimensions I would require are the final ones, not the ones first drawn. As regards brake linings I do not recommend trying another type because although there are many with greater durability they also have a higher M + this if applied to the rear only would result in extra rear braking & extra wear so that nothing would be gained. No, I do not like Lepaz we tried it once they were awkward about prices & the product was full of blow holes. I suppose they might be better now, our drum sections are smaller. One feels sure that the rough surface of a Lepaz drum must accelerate lining wear. This was our previous experience. The reason for the extra rear wear is the high temperature under the car. | ||
