Bleeding '66 Brake Question...

[Larry S.]

I have installed 2 remanufactured front brake calipers (old ones leaking) and must now bleed the lines. I understand that I start at the farthest wheel from the master cylinder (rear right wheel). The rear calipers have two bleeder screws on each caliper. Do I bleed the outer bleeder first, then the inner bleeder after?

Larry -

I do the inner rear bleeder first - works for me.

If you only worked on the front calipers, I would bleed them first and then do the rears - essentially completely flush the system with a quart of fluid so it is all fresh and moisture/contaminant free. With two bleed valves, first bleed the valve closest to the input line. There is really no "magic" way to bleed a brake system. Start with the corner/valve that is the shortest escape path for any suspected entrapped air.

If you change the master cylinder, the shortest route to purge air from the M/C to junction block line on a single MC system is out the left front.

A little intuition is all it takes - what's the shortest escape path for suspected entrapped air.
