I just reinstalled my front calipers. I bled both calipers using a Movit presure bleeder. Although the car seems to stop sufficiently fast there seems to be more pedal travel than there should be. Any thoughts comments or recommendations would be appreciated.


I have found pressure bleeding has insufficient brake fluid flow to force the air in the vertical brake lines into the calipers.

I "pedal bleed" the brakes first, after a caliper has been removed, to force the air out of the brake lines into the calipers. Unfortunately, pedal bleeding will often aerate the brake fluid in the calipers. I will then drive the car a few miles applying the brakes repeatedly to separate the air out of the aerated brake fluid. Then "pressure bleed" to get the air bubbles out of the caliper.

This procedure will require more brake fluid, however the results are often excellent.
