datsun420 Posted March 15, 2020 Report Share Posted March 15, 2020 Hey all, Having trouble finding a master cylinder. Are there any other year/models that will work? Thanks David Quote Link to comment
datzenmike Posted March 15, 2020 Report Share Posted March 15, 2020 Can you find a rebuild kit for it?? It's easier than you think to do this and I would trust this more than the crap that is re-manufactured. The 510 uses a 3/4" dual master cylinder. I don't see why any other master with the same diameter wouldn't work. The 610, 710 and B-210 also used them. Quote Link to comment
datsun420 Posted March 15, 2020 Author Report Share Posted March 15, 2020 Ok thanks, pulling it out as we speak to see the integrity of it. Quote Link to comment
banzai510(hainz) Posted March 16, 2020 Report Share Posted March 16, 2020 Is a 68 a dual or single resivore master? i had a single res master but sold it years ago Quote Link to comment
datzenmike Posted March 16, 2020 Report Share Posted March 16, 2020 Th 510 should be a dual master but the 521 truck was a single. Which reminds me... I swapped a dual from my 510 onto my 521 in the late '70s. Quote Link to comment
banzai510(hainz) Posted March 16, 2020 Report Share Posted March 16, 2020 there used to be a option to buy the 510 single resivore for 510s with dual carbs to clear 1 Quote Link to comment
datzenmike Posted March 16, 2020 Report Share Posted March 16, 2020 Scary. My first car, '64 Dodge, had a single. If you get a leak anywhere in the system ALL the brakes go out. Lines can rust out, seals wear and rubber flex lines blow up during a panic stop when line pressure spikes 10 times normal. When I was younger it was common to hear an accident was caused by 'brake failure'. Quote Link to comment
banzai510(hainz) Posted March 16, 2020 Report Share Posted March 16, 2020 Scary!!!!!!!!!!!!!!! That's everyday driving with a 521!!!!!!!!!!!!!! when it leaks from behind I change it Quote Link to comment
yenpit Posted March 23, 2020 Report Share Posted March 23, 2020 The 1968 510 was a SINGLE line master cylinder. These are GROSSLY dangerous, cuz if ONE corner of the car loses its brakes, ie split rubber hose, RWC failure etc, you lose ALL of your brakes! You can install a 69-73 DUAL line master cylinder, using all of the original dual line master components, OR you can re-plumb the hard lines as you wish, which splits the front vs rear reservoir, thus at least maintaining either front or rear brakes! It is a great upgrade on a 1968! My 1965 Mustang GT has a factory SINGLE line master................I will be upgrading it with a DUAL line master "kit", available in the aftermarket............but it's a Mustang, so there is a kit available! I would rather be safe than original, even tho it is a GT model! Quote Link to comment
yenpit Posted March 23, 2020 Report Share Posted March 23, 2020 ............ha, haven't even looked at my 521! If it is a SINGLE line master, I will be upgrading that one too! Quote Link to comment
