Another brake "job".

I'm just surprised nobody came out with a pressure bleeder 20 or 30 years ago....

Well hell, I didnt need one ever til now. Vacuum or gravity bleeding worked on every car Ive done brakes on, including my bike where it dosent like vacuum bleeding but I just have a smoke while it gravity bleeds and its good to go.

This one wanted to be picky I suppose.

Great detective work!

I wonder what scratched it?
Maybe a burr that finally broke free, or some plating that flaked off?

Did you polish the bore or get a new master?

I got a new master for 100 bucks. No where locally sold a soft goods rebuild kit for it so just bought it whole. If it wasnt the problem, screw it, as I said its 19 years old so ima chalk it up to preventive maintenance.

We got brakes. Home made pressure bleeder with a Harbor Freight pump sprayer, a spare cap from oreillys, and some tubing fittings from work, I was able to pressurize the master cylinder and got a horrific amount of bubbles out the front passenger even tho I started with both the back brakes.

At any rate, pressured all for a good while, puttin 10psi to it, after that I went around and did the normal brake pump method to finish it up and alls in workin order.

Thanks to all for the moral support.

I’ll never use anything other than a pressure bleeder after I bought mine. It makes flushes so easy.

So, I've been using a vacuum brake bleeder for a while now and after reading everyone's good luck with the pressure bleeder I just had to give it a try. I ordered the Motive (https://www.amazon.com/dp/B000TK9FE8?ref_=pe_125775000_1044873430_t_fed_asin_title&th=1) from amazon we'll see how it works.

They've existed since at least the '80s in professional form. My Dad was a certified BMW mechanic with his own shop and his looked like a propane tank split around the middle (similar to this one). In between the two halves was a diaphragm that separated the pressurized air from the fluid.
