finally i have a problem!!!

[Carbon_ZX6R]

Brake fluid is hygroscopic which means it absorbs water from the atmosphere.  Indoor or outdoor makes no difference.  The water will then sink to the lowest point, corroding things if its left long enough.

Not sure what the answer is.  I'd be tempted to get a big syringe, fill it with fresh fluid and push it back up through the system from the caliper end.  Obviously need to get a pot to catch the stuff coming out of the top.

I was wondering if it would be easier to just replace the m/c with a newer one and the same with the caliper?

brake line will be fine wont it? just blow the fluid through
?

Don't bother with the master cylinder. Do what DW suggested, push new fluid through until you're absolutely sure it's all new fluid, then bleed it and see. If it's still lacking in pressure then I'd be dismantling the M/C end of it to check for corrosion as mentioned.

I wouldn't call that easier but it might work. Depends what the root cause of the problem is.

I only say that as I was looking to upgrade the m/c and caliper like I did think front set up anyway , can't afford brembo though this time

If you're changing either of those for different types/manufacturer you'll probably need a new hose anyway because of the fittings.

Why did I let myself get drawn in to another one of your chaos-brain threads where you'll just do what you wanted to do in the first place?

Wasn't thinking different brands persay , just newer models as my understanding is there a direct replacement ,well it's not like there is anything else to talk about on here...... Yet again I'm doing a public service....
