'03 EC300 Nissin front master cyl kit?

[brider]

I can't seem to find on-line a rebuild kit for the Nissin front brake master cyl on my '03 EC300. Gotta be a common kit for many years, what's a good source, for this and the rear brake and clutch, too?

Easy as, but, as usual you dont say which planet you live on.

At some point the masters get oval bore as ally bore. Some places will offer stainless sleeve insert. Or buy another low mileage one of same size and outlet.

Check carefully the size of master cylinder. Front will be 11mm, but rears change. Cast on the side.

Touche' ! Got me there, although in this day and age I was ASSUMING an on-line source, which doesn't care which planet I live on.

I'll continue to search, but I would imagine it's common to swap in a non-Nissan M/C & lever unit with the same bore & outlet config.

Replace the Nissan with a brembo .All you need is a brembo banjo bolt as it is a different pitch but still 10mm.Putting a MC with a smaller piston will give a softer more progressive pull .Personal choice though ,I found the Nissan way too abrupt

Ahh, you want an New Zealand site

Rear brake is a little trickier, there a a couple of sizes. It will be cast into the cylinder, something like 1/2 which is a fraction of some antiquated measuring system involving inchworms or something ?

The clutch back then I'm not sure if it used DOT4 brake fluid or mineral oil. Will be written on the clutch cylinder cover.

You will need the right seals to match. DOT will be something like Nitrile and oil; EPDM, but you dont need to know that, just what type of fluid they use for the kit.

Well,first you'll need to know the brand of your clutch master, then the size .Early gassers used AJP ,Braketech or whatever they had on the shelves ,you probably find the clutches use Mineral oil (usually denoted by a green cap on the master) the brakes are Nissin ....Honda ,Yamaha ,Kawasaki every one used them .Find out the piston size and it will be easy to find

This is what you need way to much thinking going on and how the hell did a CLUTCH get involved with a FRONT BREAK question.
