Dude, you need to rebuild the master cylinder, not the caliper.

 

OOPs I have no idea why I said caliper.

Do I need the repair kit for that or not?

 

You can fit one if you like, while its apart but you shouldn't need one....I would do it if it had high miles on it.....save pulling it apart later.

 

Spanners I just looked and there is no little hole behind a larger hole.

There is only one hole in the master cylinder.

 

Oh yes there is, its tiny, almost invisible.

 

I guess I'm gonna have to get the repair kit then 'cause I can't find it.

I sucked all the brake fluid out sprayed it with brake cleaner sucked that out sprayed in some more brake cleaner then rubbed my finger in there to break up the crud and sucked it out again sprayed one last time and sucked it out again and still can't find any little hole.

 

Take pic of the inside of the master cyl and email it to me.

 

Spanners is not kidding , this little hole IS almost invisible and if its plugged up you will be tearing your hair out wondering why your brakes wont bleed/operate correctly !
Use a very bright lamp and a magnifying glass to locate this pain in the *** oriface and when you find it do not use comp. air to blow INTO the hole !
You want to suck out the crap and not blow it furthur into the master cyl.
Modify a standard wet/dry shop vac. or the wifes vacume cleaner hose end to fit snugly around this tiny hole and suck the hell out of it.
If you clear the blockage your brake system should bleed normaly , if not you will have to use a piece of wire to probe through the hole and clear the blockage , then vacume out the risidual.
As stated ... finding this little hole is half the battle.

 

I will do it tomorrow.

 

Right now I'm tempted to take off the banjo bolt and cover the big hole with my finger and shoot some air into the master cylinder where the banjo bolt goes to see if I can find it that way.
