Newer Rear brake master cyl on WR400
Posted June 17, 2007 - 01:38 AM
The other day i noticed my rear brake reservoir was starting to deform from the exhaust. Today i was working on my cousins 06 wr250 and i soon realised how much better the newer setup is. So i thought about getting one from a newer model, did a quick search and it seems other people have here too.
I was just wondering if anyone else can tell me specifics on what model bits they used for the upgrade etc.

A 2003 YZ or WR master will work fine, on the earlier models if you dont have a brake light switch, if you have a brake light switch, you may have to open up the top hole on the frame a slight bit. http://www.thumperta...ad.php?t=520704
Not sure of the geometry differences between the 03 and 07, or even if an 07 master cylinder will fit, but here's a pic of my 07 master cylinder with a brake light switch. No clearance issues or mods needed.

Looks to be an easy job, my bike doesn't have the rear brake switch but i wouldn't mind wiring one in.
