Re: Problem with Hel lines, possible Master cylinder mod?
 

I got a set of HEL lines about a month ago and the same happened to me (metric coarse v. metric fine, apparently ....). When I called HEL* they were v. apologetic and told me I'd been sent the bolt kit for an 'S' rather than an 'N'. Not sure if that's true but the bolt they sent fitted perfectly.

* Called them at 4.30pm on a Tuesday and the bolt was with me at 9.30am the next day !!!!

did they send you a fine thread?

Re: Problem with Hel lines, possible Master cylinder mod?
 

Wrong bolt they sent you.

It wont fit a standard nissin MC but the radial nissin uses metric fine thread and it fitted that, the SV standard should be metric corse as everyone said, just compare the original bolt to the HEL one.

Same thread.

The one they sent was the same as the original (actually they sent a couple of both just to be on the safe side). Delayed things by 20 hours, but once they were on they were great. No more furry connectors !!!

what is the size of the thread im after? i measured it at work and i got an M10 x 2mm but apparently hel make no such thing! this is starting to be a real pain in the ****, i paid £70 for this kit and expect it to fit! i know i over paid but i got it from my friend's business and thought it would be the safe option!!! :smt019 should have stuck with ebay

Re: Problem with Hel lines, possible Master cylinder mod?
 

Not 100% (can measure when I get home at 5pm ish) but I think the standard SV mastercylinder thread is M10 x 1.00

Re: Problem with Hel lines, possible Master cylinder mod?
 

Yeap, its 1.00 pitch thread!

Afternoon all.

There are only 2 different threads you will normally encounter on Jap master cylinders, 10x1.25mm & 10x1mm.

Ask them to send you the 'other' one to the one that you have. if that makes sense. Generally Nissin use 10x1.25mm threads.


Cheers.

There are only 2 different threads you will normally encounter on Jap master cylinders, 10x1.25mm & 10x1mm. Your front caliper mounting bolts should be 10x1.25 mm pitch, whip one out, give it a clean & see if it fits the master cylinder. If it does, Bingo! You'll know which one to ask for.

Alternatively, ask them to send you the 'other' one to the one that you have. if that makes sense. Generally Nissin use 10x1.25mm threads.
