Brakes adjustments

(1/3) > >>

El__burro:
Good day, i have almost finished my project (just left to change the rear tyre and complete registration of my cb750 k2).

After having filled up my front brake system with oil i have a problem.
The front wheel is pretty hard to turn as the brakes pads are holding on the disks.
I have a dual front brake.
The disks seem pretty straight.

Any ideas for sorting this out.

Thanks a lot

Johnwebley:
when I fitted dual discs I had that issue on the OS/new side,
the caliper alignment is crucial,as it needs to press the pads directly onto the disc,

I was lucky,I could ride the bike,then check the rubbing part of the pad,and make adjustments with a file,

try removing the pads,then see how well the caliper meets up with the disc,
you might find either the top,or bottom touch first,

does the lever feel soft/spongy ??

make sure the moving pad slides in the caliper easily,

El__burro:
it looks like the moving pad on one side ( the other is fine) that doesn't retract.
I guess i need to remove the calliper and inspect it to work out why is not sliding in.
the lever feels soft, no friction or pressure.

thanks

NigelWilmshurst:
I had the same problem on my twin disc conversion, after lots of headache I realised the piston seals I had ordered from David silver were too big and not allowing the pistons to return freely, which also created drag on full lock, ordered the correct seals through my local honda dealer and filed the pads.

Eventually sorted the problem out, the lever feels slightly spongy but actually works fine, the F2 reservoir may of been a better choice as it's bigger.

El__burro:
i thought of removing the calliper to have a look but then i realised that the disk is probably not straight as when i spin the wheel it goes free one a side and stuck for another bit.
if that is my problem, how easy is to fix.

Thanks
