I'm typing this for my husband Joe..he's replaced the vaccum booster/master cylinder twice within the past 2 days. He's bled the brakes by hand and still getting air in the lines abd a spongy brake pedal.

He's at his wit's end and can't think what else could be the matter.
Can anyone give him some other ideas to checkto seewhy he's still not getting all the air out of the lines/spongy brake?

Thanks.

 

got to be a pin hole in one the brake lines. Might even have leak in caliper. Clean up everything with brake fluid and look close. Got to be a leak or a really bad hose that may be bulging.
