Possible leak when bleeding brakes....but where!?

So to sum, should have bought some m596s

Just one other thing then which may already have been mentioned, but do you have a bleed block in the caliper when pulling the lever at that phase of the bleed? Good luck, hope you get it sorted. It s satisfying to get something sorted all yourself. Incidentally, I got rid of my Avids and swapped for shimano brakes because the Avids were a pain in the arse on every front, unreliable and bloody awkward to bleed. Shimano brakes are dead easy. Guess that's perhaps not useful advice at this stage!

Chunkers1980

No, so that's why we gave it to him before!

bernie1973

Yes, but sadly you lacked the telepathic foresight to dispense this advice before he bought the Avids!

Chunkers1980

No I didn't, we told him in another thread.

I told him they are 10 years old in design nearly, am shimano would suit much better. He was concerned about weight for some unknown reason.

I'm sure I can quite easily go out and buy some second hand m596s that are messed up too.
Getting hold of a bad set of brakes doesn't mean they're all bad. Maybe you had one bad experience and you wussed out.
My brother's avid juicy's have been on his bike atleast 6 years and not one problem from there

Just got off the phone to another bike shop and he said without actually taking a look at it himself he can't really say where the leak is...money money money.
I think I'm just going to take the lever apart myself and find out which bits are damaged. There are about 3 different lever service kits so need to make sure I get the one with the right bits.
The guy I spoke to mentioned the lever rod or piston kit which wasn't what I had been looking at.
So time to crack em open I think. Looking forward to it!

Good luck, but Just on the off chance that you irreparably damage the unit in your travails, I'd get Shimano as a replacement.

I'd try a 'professional' bleed first.
I've only bled Avids once, in not ideal conditions in the parking lot at Swinley. but initially I just made it worse - same thing, air just seemed to be appearing from nowhere.
Took half an hour of faffing to get it sorted. Still don't know what was wrong. I just took everything off, started over and it worked.
But I did some serious swearing first.
Silly bugger had split the calipers instead of loosening the caliper bolts to centre them.

What do you mean a professional bleed? I've just been following the avid/sram instrucitons which as far as I know cover everything.
Do you mean flush it through?

Nope, someone who does it for a living, or at least has done it successfully before.
