Downunder

I bleed my matco by sucking through from top to bottom. (Vacuum on nipple and operate brake lever)

I bought a cheap brake suction kit on ebay.

Some caliper nipples are on the bottom of the calipers. I think these are better suited to a push through system. Forcing air through and out the top.

As my matco nipples are on the top of the caliper (and the oil line at the bottom), I prefer to suck through them to remove the air.

You WILL want a park brake.
