i run a porshing valve teed off my rear brakes that runs to one off the front brake calipars. when it hit the rear brake pedal it works both front brake and rear.

i have and double banjo bolt in the rear brake with 2 lines one goes to the rear. the other goes through the adjustable valve then to the front brake calipar.

i have run this set up for years . the trouble is i cant get it to bleed. have push fluid through both calipars , and tried suction as well. the rear is fine its the front calipar.

any ideals ?

thanks for the help.

 

I know on a car you have to get a special tool that holds open the proportioning valve, I made one for a jeep I had to bleed the brakes on. Basically it was just a piece of thin steel with a u shaped slot in it. Post a pic of the valve.
