Floating Bell Brake Discs
FITS THE FOLLOWING MODELS:
Our Race specification Float in the Bell Brake Disc Bells are ideal for heavy duty applications, especially when using larger discs as these should be mounted to allow axial float and radial heat expansion of the disc.
Radial float allows differential expansion of disc and bell thus reducing stresses in the disc and minimising disc cracking and distortion.
The idea of axial float is to compensate for a certain amount of stub axle / upright flex by allowing the disc to take up its ideal position within the range of float thus avoiding "knockback" of the caliper pistons.
However the float should not be excessive as disc gyroscopic loads can cause the same effect that the float is trying to alleviate.
The amount of axial float will depend somewhat on the application, we have found that for the later Lotus application with minimal disc movement relative to the caliper the amount of float need only be around 0.15 - 0.2mm.
Our floating Disc Bells are the pinnacle, made from Aircraft specification certificated 7075 aluminium, Black Hard anodised for the ultimate in corrosion and wear resistance.
We use the highest quality Titanium for the 12 Disc-Bell bobbins even these are then anodised to reduce the galling that can be caused by constant movement and expansion between the Bell and Disc Bobbin.
The fasteners we use are again the highest specification ‘K’ locknuts and specially manufactured 12.9 grade Low Head Cap head fasteners which are Delta coated for longest corrosion protection possible.
Anything but our special Low Head fasteners may touch the caliper when used on some discs.
