A bit confused - reading up on Master Cyls and i'm wondering as to the diffs between inline and radial configurations. Reason i'm confused is you bleed Shimano's (inline?) from M Cyl to Caliper yet a Maint book i'm reading shows an XTR Cyl being bled as per for Radials and the Shimano Bleed Kit is set up for Radials...are XTR's radial or am i losing the plot? :?

    what do you mean by radials?

    the XTR bleed the same as all shimanos brakes.

    It's what i read here...

    ...and what is explained in what appears to be a decent-enough book "Mountain bike maintenance" by Guy Andrews.
    I'm pretty conversant with M/cycle brakes where Radial (caliper mounting) doesn't seem to match with what the article says. So i don't know what i mean by Radial, hence the query. [/url]

    Best thing to do is download the manual from Shimano.

    Many brakes can be bled in different ways.

    nothing on there about XTR brakes. which are best bled with fluid from the caliper to the lever.

    as Sonic says read the manual.

    Ta for the info re Shimano techdoc's - what a fantastic resource! Still don't know about Radial m/cyls, though (maybe it was a turn of phrase or something). Anyway, cheers Folks :D

    Radial master cylinder is a bit of jargon from motorbikes really, it's fairly meaningless though, just refers to m/cs where the piston is perpendicular to the lever.

    Radial:

    Axial, or conventional:

    It makes no difference to how you bleed the brakes though, it's just a layout/packaging thing.
