brake bleeding problem

[pyrie]

Hi,
I was trying to bleed my brake fluid, but when I unscrewed the bleed valve a half turn, no fluid came out.

Even when I took the bleed valve out, still, no brake fluid. So, it must be clogged up somewhere.

Any ideas on how I can locate the problem and how to fix it?

Sounds like the same problem I had.

Try removing the line leading to the caliper and seeing if you get fluid there. If you do, then you know the caliper is blocked up. Sometimes, tapping the caliper with a mallet is enough to loosen the blockage. But usually, it means you have to either rebuild or replace the caliper.

Yeah, that's what I was afraid for. I hoped I could fix the problem without disconnecting the line leading to the caliper or the caliper itself.
It won't be an 1 hours job

Thanks for the reply and foto's of the caliper!

Just to be a step ahead,
What if the caliper isn't the problem, but what if the line itself is blocked?
How do I clean that?
