Hello all, I have a '64 Riviera and the single master cylinder 4wheel drum setup kinda scares me. what r some of my options? i see some guy on eBay has a kit to put mid 70's Riviera disk/master cylinder on the '64? or maybe just a dual master cylinder swap? thanks
Contact scarebird for a conversion kit. I believe they also sell on Ebay. http://www.scarebird.com/6928.html
mine are from scarebird.i will put them under a 64 wildcat. i tried them on a set of 65 riv spindles and they fit perfect.
Hi Could you please detail your Scarebird disc brake conversion on your 64 Cat, specifically the parts? I am interested in what you used for master cylinder, vacuum booster, proportioning valve, lines, etc. Did you change the rears? Thanks Dan
i will put them thursday the 22 on my wildcat,and i will trie it with the stock booster and mastercylinder.i hope it will work,when it's not working i will pull the mastercylinder from my brothers chevy c10 from 1982(it had a very bad accident a few weeks ago)incl prop valve. scarebird says you need; 71-76 riv rotors napa# 85537 71-76 riv calipers napa# 442-2000 and 442-2001 71-76 riv brake pads napa# ae728am 71-76 riv brake hose 15" napa# 36646 i will trie it with my original brake hose,because they ar about 14" long for the mastercylinder scarebird recommends 71-76 riv and a adjustable prop valve. And i will try to put the frontdrums on the rear.
Thanks for the info. I look forward to the update. Do the factory wheels fit over the caliper? I have 64 factory mags and would hate to give them up. I have been told the original master cylinder will work but must keep a close eye on the fluid. It goes down quickly as the pads wear. Dan
i did the conversion today,it is a very thight fit. only now my car is braking harder in the rear then in the front. i will put a proportioning valve in it and then it will be ok. i have steel wheels with a deeper backspace then my original ones and they fit perfect. pictures follow
That makes sense from what I am learning about these conversions. What year steel wheels or back spacing are you using? If you change master cylinders, do you think you will need to change vacuum boosters? Somewhere in the archives of this forum someone posted theory/practice on master cylinders and vacuum boosters as well as proportioning/check valve installation.
are you going to use an OEM type prop valve or an after market adjustable type? Also, when I asked Pirate Jack what they had for my Riviera, this is what they said: Our master cylinders are for GM vehicles so it will work for you. We have master cylinder and proportioning valves but no line kits. I would recommend Classic Tube or Inline Tube for your brake lines. thanks for all the good info.
I want to use a oem type prop valve,they are made to work on disk-drum. I'm thinking of switching my brothers mastercylinder and prop valve from his pickup in the wildcat(that stuff is all for free,and it's all working good).
Thanks for the info. Inline Tube has all the GM booster & valves. It looks like they suggest going to a 3/8" brake line over a 1/4" . I never thought of going to a bigger brake line. I guess it makes sense.
Where did you see the advice about using 3/8" brake line? I could use some more advice on building my new system and for what i remembering my physics, it shouldn't make a difference. thanks
I think Inline Tube. It was under Disc Conversion or Custom applications towards the bottom. I have been meaning to contact them. I was going to replace all my lines with stainless and the more I read the more confused I became. I hate to give up the factory 1964 mags.
I spoke to Inline Tube today. At first, the sales rep said no such advice existed on their website suggesting brake live size change. He was actually kind of a jerk. I went back to their web site , and it sure is there. I misread the sizes. The upgrade is downsizing the diameter of the line, 1/4" to 3/16". I called back and got a salesman who actually likes old cars and said the suggestion is accurate. The smaller diameter gives better pedal feel with disc brakes . I am thinking about having stainless steel emergency brake cables templated there. Anyone interested?
