Master Cylinder

[billwest]

Hi,

I currently run blue-spot calipers on the front brakes, and found an FJR master cylinder.  This master cylinder happens to be for ABS, which my FJ does not have.  Does anyone foresee any problems with this setup?

Also, I am overhauling this master cylinder, and I'll be blowed if I can get the piston out.  Compressed air maybe?

Cheers,

Bill.

Bill.......should be no problems with the master cylinder.....
Does it have 3 pins on the micro-switch or 2?
If 2, just plug the wires straight on.
If 3, either swap the old micro-switch onto it, or figure out which 2 connectors you need to use by trial and error.

Is the piston retained by a circlip? as in the OEM master?

Thanks Harvy,

It has 2 pins.

I removed the circlip, but whatever lies beneath is stuck solid.

Take a look at this Bill:

It would seem that the piston SHOULD come out once the circlip is removed.......it must be all gunged up.
If you use compressed air, make sure you aim it into a bucket or some sort of container, just in case it decides to let go all of a sudden and you end up with parts all over the garage floor.

Looks like immediately behind the circlip is a rubber seal.......maybe its shagged and binding the piston?

Done!  I took it to the local tyre and brake place.  Their compressor is bigger than mine.  It took a couple of goes, but it eventually came flying out.

Now, for a rebuild kit.  Ex-Japan (2 weeks waiting), local price $126AUS from Yamahahaha

Might try a supplier in the US (around $40US + postage) or UK, I think.

There ya go......... Get the kit from the US mate.
That site I posted has it for US$30 odd.......... even with air freight you are a long way in front.

Just ordered it from boats.net !

Cost: $50AUS.

Instead of using compressed air (which sometimes doesn't work if things are really tight), you can leave the fluid in it and just use hydraulic force to push stuff out (if it's in at least sorta working condition).  Much safer, much more controllable, and you can generate huge pressures very easily.

Of course, you need to be very careful about blowing evil paint-eating fluid all over, but you need to worry that when using compressed air too.

Agreed, but the thing wasn't on the bike.  I had it shipped over from the US.
