I'm building a traditional T,I have 46 ford rear drum brakes with 54 ford F-1 front drum brakes.I'm using 67 ford mustang drum/drum master cylinder mounted below floor. I searched post on if you need to run residual pressure valves in line,or if they are built into the master cylinder. I put the blunt end of a small drill bit in the outlets and appears to go all the way to bore no resistance. So should i assume there are no rpv valves in the master cylinder? Thanks for any info.
yep, needs valves, I use a 72 maverick mc, should be the same only it has the valves built in. not much help now that you've already got the mootang mc, but it will on the next one.
I am using the same kind of brake setup and I always had to sort of give the brakes one short pump before I'd get full pedal...........put in rpv's (10 lb) and it made no difference.....I still have to pump it once lightly before I can apply full brakes.......I am using '48 Merc(Ford) drums on front and rear.......same master cylinder under the floor.... Do you have to pump it before you get full pedal? CB
nope, on the shoebox it sat all winter unused, and got in fired it up, stepped on teh brakes and they were fine. have you checked your brake adjustments?
Haven't got the brake lines all run yet.Just trying to get it right the first time. Does the 72 maverick master cylinder have rpv valve built into them?
I'm usin' F1 fronts, LTD rears Cougar master cylinder. I'm puttin' in the check valves just in case. It's been said that a couple pounds of pressure keeps the wheel cylinder cups sealed up. If the master cylinder and the line has check valves it doesn't hurt anything. I like to save a buck too but, the hassles later without the vales is not worth the risk to me. Smokey Hi Brucie... see ya at the Showdown I hope...
I'll be there, Smoke........what I will be driving is open right now......maybe Coo-Pay......maybe Honda CRV.........of course, it'll be my *traditional* CRV Brucie ;^)
