    Grimeca system 8

    I have Grimeca system 8 disc brakes on my bike. Does anyone know where I can find the owner's manual for these brakes? I can't find a website with any information on them.

    Clone of the Shimano XT m755/SRAM 9.0 disc brake. This one uses DOT fluid. They come with braided steel hoses. I think at the time, the brakes were more marketed towards the XC crowd.

    Owner manual won't really tell you anything... what do you want to know?

    * Weight: 292g (lever, caliper & line)
    * Body: aluminium housing with reservoire
    * Lever: lightweight hydraulic lever in an ergonomic design
    * Compatibility: brake lever fits w/twisters & triggers
    * Technology: fixed four piston capiler design (with self adjusting pistons) for silent, drag-free performance

    It's an IS caliper designed to fit 160mm rotors. Rear can be used on the front to fit 180mm rotor. Front can be used on rear to fit 140mm rotor. Adapters can be used to fit larger rotors. Rotors were 6-bolt rotors. Bolts were all pretty standard stuff.

    I was looking for the bleeding instructions. Might come in handy should I need to bled them. I think they may need new pads. They stop me well but I can't get them to lock up the front or rear.

    Bleeding is done the same way as the Shimano brakes (except you use DOT fluid). You can gravity bleed. Or you can pump the brake while opening and closing the bleed nut. The concept is the same as bleeding a car or motorcycle brake.

    Brake pads are the same as the XT m755 and I believe the 4 piston Hopes. They are still easily found.

    i've had best results bleeding the shimano version from the bottom-up using a syringe full of mineral oil and a tube to inject it into the caliper allowing the bubbles to be assisted by gravity to make their way to the resivouir. i take the pads out then push oil through the system whilst tapping the caliper and hose till no more bubbles arise from the lever then bleed top down whilst pumping the lever and tightening the bleed nipple alternatively.

    There is a clear plastic tubing that covers the stainless hoses. Can I remove that tubing to show off the hoses? It serves no practical use that I can see.

    If they're clear, you can still see the stainless. Leave them on, it protects the frame.

    They are clear to a point. They look a bit smokey.
