1989 GL 1500 trike converted drum to caliper brakes

[afunnydadd]

first off great site!..so much great info has helped allot...but i did a conversion from drum brakes to caliper using the stock rear master cylinder but cannot get a solid brake pedal. I have tried the hold down trick, run two bottles of brake fluid without results. It has new brake lines on the rear, i rebuilt the master cylinder, bought a vac bleeder kit..i get some air but when it gets clear, no bubbles i still dont have a solid pedal.its really crazy...thinking the master cylinder is bypassing...please help!..thanks!!

is the rear pedal still hooked up to the front left caliper?

[afunnydadd]

yes sir it bleeds with no air

You might not have enough volume from that master for the three calipers.

[afunnydadd]

ok..so do i need to block the front caliper?

[Rambozo]

You could tie the two front calipers to the hand brake, and the two rear to the foot brake, or check with a trike shop for a larger rear master. I'm sure there are a few solutions out there. First would be to make sure everything you have is in good shape and working properly. Pressure tests, etc.

I did notice that I don't have the pressure on the back calipers that I have on the front caliper..I may block the front at the master Cylinder and see what happens...I'm just so worn down from bleeding this thing ¡
