brake line size again
What size brake line comes out of the new proportioning valves? MY brake lines are from drum brakes and have I/4 down to the cross member and tee off to 3/16. The line to the rear is 1/4 inch back to the rear end then tees off to 3/16 across to the drums .My lines are in good shape and I want to use them with my new disc brakes . I haven't got my new master and booster set up . Can I use the lines I have? Thanks for any info.

Re: brake line size again
stock 73-87 trucks use 1/4" feed to valve or tee depending on style . then there dropped to 3/16" to each wheel . and the rear is feed 1/4" to hose at axle then hose end splits it to 3/16"
