1961 Volvo P1800 project, part 18

Brakes

I managed to get the very last rebuilt early caliper from VP-Auto Parts, a left unit. However, knowing what I know now I would have just rebuilt my calipers. What precious information is it? Read on.

The pistons were stuck in the bores but after a couple of days soaking in the vinegar I gave the piston a good smack. This may seem counter intuitive but it helped loosening the piston in the bore.

Using industrial size wise grips I was able to turn and eventually lift up the pistons.

This is the cool part. It is ONLY the seal that wears in the bores. On later model calipers the bore is fitted perfectly to the piston and it can not have any flaws or rust. In this case, all I have to do is clean up the groove for the seals and we are off to the races.

I think I will take to money I save on rebuilding these my self and buy a blast cabinet and clean these babies to perfection. There is NO limit on how many tools a man can have.
