Matco Brakes
I have attached a drawing of the PH6 series Matco caliper
to this note. If you look at this drawing of the caliper
it is obvious why we have such a hard time bleeding them.
The position of the fluid passages relative to a horizontal
line thru each piston hole at the output side will show
where and how much air can be trapped. On my calipers the
pistons are hollow cups so it makes the trapped air worse.
You might want to print out the drawing and then you can
position it like your installed calipers and draw a
horizontal line on the diagram to assist you in determining
how much trapped air you might have and how you might
position the caliper to expel the air. Remember to start
with the piston closest to the fluid inlet for the
positioning. Those with retracts might get good results by
retracting the gear most of the way then trying bleeding
since the air would move to the back of the piston
cylinders. Your mileage may vary! Hope this helps.
This is not a design deficiency, just a matter of caliper positioning.
