Alternate 510 master cylinder

[Rustina 510]

So draynor1995 has a master cylinder going out on his 510 wagon and brake flui is going onto the floor boards it's gettin so bad.

 

We can locate a new master cylinder so... Will any other "easier to find" master cylinders work?

 

Please help and thx

I have never tried but I have heard a early 200sx will work. I know a 280z one will fit, as i have one on my dime, but may be kinda firm for pedal feel as it is a bigger bore than stock.

Yes for a stock system a larger diameter master is NOT and upgrade. It only makes working the brakes harder.

 

What is the 510, a 3/4" master? I think the 710 is also 3/4". I put a later S110 (200sx) 13/16 (that's 1/16" larger) on my 710 and the peddle is noticeably firmer. It's ... ok but wouldn't want more.

[Draynor]

what year 200 sx should we be looking for the master cylinder mike? and thx for the help... again

[Draynor]

1979-83 right

[Rustina 510]

Yeah 79-83 should be the one we are looking for, I think that's te s110

[hobbes_the_cat]

I was thinking 77-79 200sx might fit. The stock 510 is a 3/4" master

[Draynor]

wasnt the s110 200sx 79-83?

[datzenmike]

The S10 '77-'79 200sx has a 3/4" master and so does the 610/710/B-210 and they share the same piston cup part number. This doesn't mean the master is exactly the same ... just 3/4" but likely to fit.

 

The 620 is also 3/4" but the outlets are facing the fender and won't clear the strut tower on a car.

 

 

Second gen 200sx is the S110 '80-'83 and they had 13/16" master '80-'81. The '82-'83 S110 used a 7/8" master

[Draynor]

Thanks Mike!

Datzenmike, kickin ass again.

[datzenmike]

meh..... it was a slow night.

I put a 7/8 240z one in my 68 510 and I love it

had to tweak the brake lines slightly to line up properly just be easy on the bends

Rock Auto has the correct master cylinder for pretty cheap, but I have and still use a 1978 Datsun 510 master cylinder in my 1969 race wagon.

[datzenmike]

Yeah that's a 13/16" on the A10. You probably have larger calipers on it?
