It's true.

I think people should be able to ask an off topic/year question once in awhile. Especially someone who has offered help to many others in the past. I appreciate any knowledge I might gain, even if it doesn't necessarily apply to an older vehicle. Who knows, maybe it will.

I got one useful suggestion. Is there a specific test I can perform to confirm the MC is gone? | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 |
They say money can't buy happiness. It can buy old Chevy trucks though. Same thing. 1972 Chevy c10 Cheyenne SuperIn the Gallery Forum | | | | | | Anonymous Unregistered | | Anonymous Unregistered | Drum rear, disc front.
I have since been educated that the larger (rear) section of the master cylinder is for the front brakes (large volume needed for calipiers) and the smaller section of the master cylinder is for the rear brakes. Therefore the frothy brake fluid is from the front brakes. | | | | | Joined: Jun 2004 Posts: 336 Member | | Member Joined: Jun 2004 Posts: 336 | What are the symptoms of a master cylinder giving up the ghost?
