Subject:      Lower bleeder screw question (searched archives)
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

Hi all.

Amongst other things, I've installed a new MC. I bench bled it til
fluid came out, installed. bled at MC, then gravity bled brakes. They
felt ok, but not really efficient. I started to bleed them again with
a one man one way valve hose but it popped off the RR so I went with
straight hose on the rest. I would pump about 10x's per wheel then on
last stroke, kept pedal down with piece of wood braced against seat,
then shut bleeder screw. Regardless, no improvement. In fact worse.
Pedal travels too far. Rears were adjusted not long ago.

I'm making a power bleeder and using that before taking to a brake
shop to have them bleed my brakes.

I have read that the lower bleeder screw on each caliper is for
draining only . I have also read that on the early two piston type
calipers, that one needs to bleed upper and lower bleeder screw on
each caliper.

Frankly I do not know for sure if I have the two piston model, but I
DO have two screws per caliper.

Do I bleed at upper AND lower screws on calipers?

Even if lower for drain (as per Bentley) will bleeding it help?

Thanks for any help, and sorry for long post.

Neil.
