Tried to re bleed my brakes last night - got some air but kept hearing a whistling of sorts and the brake pedal would go soft again after I had just got pedal. Sound coming from the Master cyl so I"m pretty sure I've got a bad seal and it's all blow by.

Therefore I need one. Master Cyl. For RHD. I know there are a ton of guys out there who shipped clips and didn't use theirs. hit me up.

I got one of those!

Let me know

sadly I haven't found EXACTLY what I'm looking for yet. Apparently there is a difference between a master cyl in a ss3 and a gt4.... who knew.

The top one is the one I need. The bottom one is the one that I've found is most common
They are aligned such that the mounting flanges are in the same spot. So you can see the obvious length difference and the o-ring difference from where it mounts into the brake booster (shaft, extended male end etc.)
