Howsit 

 

So i had these brakes bled, new pads, cleaned rotors and adjusted the contact points. 

 

I have no stopping power on the front and the back is meh, 

 

Anyone have any idea what the issue could be? Its almost as if there is no piston travel. I use them on my commuter and **** its getting a bit ridiculous now, scary 

[V12man]

Take them to someone who can bleed them properly....

Agree with V12...

 

Did you use the correct fluid?

[Swany05]

My LBS did, he mentioned that they may need to be serviced, something about the MC diaphragm. I have searched high and low and cant find anything pertaining to them being serviceable

will probably be cheaper to buy a better set of brakes secondhand than try and fix those. If a bleed didn't fix it, they are probably fubar, especially if they are not serviceable

[Swany05]

Yeah this is what my next step would be, 

 

So much for budget commuter LOL

^^^^^^ This. Currently rocking a set of these on my enduro rig coz my other brakes died on me. More  than sufficient for a commuter, and a breeze to bleed yourself

[Swany05]

Sweet 

 

Have sent him a pm already 

 

Thanks man

Let him confirm the length before you buy. had to lengthen my hoses on my 615's and it put me back R700 for the aftermarket hose kit alone. At least I have the kit at home to bleed it myself, else it would add about another R150 per side for the bleed at a bikeshop

Good point, if they aren't long enough I'll have a look for a kit that is. Buying new is not really an option at this stage,

DIY bleed kit is easy for Shimano. 

 

Medium sized syringe from pharmacy that you can screw into the fill hole on the master cylinder at the lever and you can then fill with fluid which will act as the funnel.

 

4-5mm clear tubing that you can get at pool shop or pet shop (fish tank supplies) that you can connect to the bleed valve on the caliper. You only need a very short length.

 

Small clear container, drill hole in top of and insert other end of clear tubing, to catch the fluid as you bleed the brakes.  If you don't have a container, jiffy bag with tube inserted and tied tight at the top with elastic band so does not slide off.

 

Your LBS should be able to sell you brake hose per meter and you might be able to reuse the o-rings, else get from LBS who usually have some lying around if you ask nicely.....

 

Edit:  Some pics to make it easier to understand.  If the syringe point is small enough it will screw direct into the bleed hole (without the need for the adapter that is mentioned) http://www.epicbleedsolutions.com/blog/how-to-bleed-new-shimano-brakes/

Awesome advice man thanks

 

I think i may already have all the parts at home. 

 

Shimano ftw.

My view is that they did not bleed them properly... not all LBS tech's are equal, and bleeding them should not subtract from their prior performance - even if the diaphram is dodgy.

 

You will probably struggle to find a service kit locally if one is even available- maybe ebay?
