BLKMGK Posted September 17, 2001 Share Posted September 17, 2001 Okay, jumped on the gas for a friend and ended up having to really hit the brakes afterwards. It's now QUITE apparent that I need a prop valve pretty badly. (ahem) How hard is this to install? I did it once on my Mustang but the stock lines had fittings that worked fine. I ASSume the Datsun uses metric fittings? Can this be easily adapted? I figure the firewall up front is as good a place as any to install it and if i can I'd liek to keep cutting and flaring to a BARE minimum as I've not got the proper tools on hand. Any tips would be welcome - as much as I'd like ot put it in the tunnel like Pete I don't think it's going to happen Booster question. Sometimes the pedal seems to go lower than others, much lower it seems like once in awhile. I don't recall this ever occuring with the old brakes but everything is new including the master except for the booster. A second stab at the brakes provides much more pressure on the rare occasion that this occurs. Am I looking at needing a new booster? I THINK I might have one spare but I don't want to swap it unless this truly is the right fix. IF I must swap is there a bolt-in part that provides any advantage? I think the 2+2 booster is too big with the clutch master in there on a 72, yes? Last question - since I'll be cracking into the brakes again anyway.. how hard is a line lock to install? I've actually got one spare in the garage but again I think it's fittings are likely to be English and not Metric. Is there a "best" spot to install this? My unit was made by Hurst. Thanks!!!!!

Modern Motorsports Ltd Posted September 17, 2001 Share Posted September 17, 2001 Here's the 'edelman' fitting list a friend supplied me with, this was all he needed to put one in his 280zx and I doubt our fittings are very different if at all. Took him less than 30 minutes total....I only wish mine was as simple but fittings aren't available up here. 2 each 261320 1/8 ntp to 3/16 flare male. 2 each 270300 3/16 flare female to 10mm male. 3 each 274000 10mm female to 10mm female. The hard to find parts are the metric to imperial adaptors.....some UPA Napas (stateside only) carry edelman. I got all but one of the above PN's so still need to roust up the remaining parts needed. Hope that helps. Quote Link to comment Share on other sites More sharing options...
BLKMGK Posted September 18, 2001 Author Share Posted September 18, 2001 Ross, where was this installed at? Is there an easy place to crack open the line to the rear for this? Anyone have ideas on the booster? It's pretty disconcerting Would the line lock go in much the same way as the prop valve - wadapters like those listed above? I'll admit I've not yet looked under the hood but I'm hoping to avoid bending lines Quote Link to comment Share on other sites More sharing options...
pparaska Posted September 18, 2001 Share Posted September 18, 2001 Fun with the metric to SAE adapters, huh? Is the booster problem just a problem with the cam not giving the engine enough vacuum? Are you SURE you fixed all the vacuum leaks? What is the idle vacuum? Quote Link to comment Share on other sites More sharing options...
