Vacum bleeding may not be good enough to reset the valve. I had a similar problem first time working on my brakes. I would recomend bleeding the old fashion way with someone pumping the brakes for you and you bleeding at each weel here is the sequence Left rear inner Left rear outer Right rear inner Right rear outer Left front Right front after blleeding pump hard 2-3 times brake light should go out.

There is a reset procedure for resetting the proportioning valve.  Someone may correct me but I believe it is to bleed the brakes and eliminate any leaks then apply "significant" pressure to the brake pedal and the valve will reset.

http://www.volvette.com/c-brake73-77.html have you tried these guys for the part?  I think i kept the p-val from my 78 when i reworked the brakes in feb 09 (it worked fine but i installed a line lock and wanted all new equip)i will look this weekend, from the pictures they look the same.

robert and chip-- i bled the brakes in the proper order and the only small drip is coming from a connection on the proportioning valve. it doesnt squirt out when brake is pushed but is not pouring out. i have also pressed on the brake pedal hard enough that is should be reset. after 34 years it may just be time to replace it.

howard thanks for that site. they are selling them for $40 less than ecklers. will call them tomorrow and see if they have it in stock and if they do will order it from them and cancel ecklers.

Dave, keep in mind that Ecklers sells 2 versions. The authentic looking brass model at $120 and the alum. style at $60., just as good, looks different. And then too, have you checked with "Corvette Specialties"?

jim, saw that after i read your post but the aluminum version says that the electric doesn't match up for a 75. called volunteer vette parts as howard suggested and they ran out of them too. guess this is the year for these valves to go.

i guess if all else fails, i might have to cut the floor pan out and be like fred flintstone

haven't been on for a few. thanks joe for the tip. will call them monday morning and see if they have it. pulled the old one out finally and found out where it was leaking and why it is not working.there is a connection that the back brake line screws into. i unscrewed it from the valve and on the top of the connection it has what looks like a freeze plug. there is a small rubber diaphram under the cap. i know this because the cap was not there. will try that link joe suggested mon and hope i get it soon.

kind of rots as i have 2 corvettes and can't use either one
