Deore M615 problem

VolatileMike

So I bought some of these new. I did a few things wrong:

a) started it late, not leaving much time.

b) cluttered workspace/couldn't find tools

Anyway despite this I followed this guide:
http://www.epicbleedsolutions.com/blog/ ... -bleeding/

I thought it was going well until the final stages when told to press the brake lever multiple times, and then brake fluid leaked out of the lever connection...I looked at it and the olive had not contacted properly and was a bit mangled.

So, do I need to bleed this brake? or can I just trim hose a little with new olive and end then refit?

Thanks

As most people need to bleed the brakes went they try to do anything that does not "need" bleeding you might still be ok but I would think not.

If fluid got out, then it's likely that air got drawn into the system to replace it when the lever pressure was released, so yes, you may well need to bleed the brake after you've finally sorted the connection.

Guess I will need a bleed kit then. Has anyone used the one on this site? http://www.epicbleedsolutions.com/produ ... plete-kit/

Yes, and I won't use anything else - cheap and work.

VolatileMike

Ordered. Lets see how this goes!

I ordered one on Thursday, should he here today. I didn't want to take the risk shortening mine last week as I knew I was riding yesterday.

So an update on this

I got them fitted, they are squealing like hell though. Like a train coming.

Do I need to sand the pads a bit?

I'd hazard a guess that they need bedding in.

are they stopping you but just squealing? are they the OE resin pads?

Bed them in, failing that, centre them.

Different ways of centreing them. You could loosen the caliper bolts (bolts that hold brake caliper onto forks/frame), and then visually align the caliper so that you've got a bit of space on both sides of the rotor.

The proper way is to loosen the caliper bolts, pull the brake lever at handlebar (so the pads close around the rotor), then whilst still holding the brake lever - retighten the bolts.

are your existing disks clean they may have residue on from when youve cleaned your bike try giving them a wipe with white spirits .
Always worth getting a bleed kit and doing it yourself ,once youve done it you realise how easy it is to do and saves you taking it to a shop.

Yep they do stop, and yes OE pads.

They probably do need bedding in I imagine, will try that also as they are faintly rubbing.

I did bleed them myself, for the first time :oops:

thought I made a mess of it, but the brake levers dont seem spongey so think its all good. I thought I could have contaminated the pads but I guess if they were contaminated the brakes wouldn't stop?
