Fitting new brake discs to your bike

At some point every bike will wear out its discs. Wether that is due to wear limits being breached due to high mileage or maybe your brake pads have been binding and your discs have warped. These are the 2 main reasons for needing replacements. Some other reasons may be excessive disc float where the alloy hub becomes damaged where the outer rotor sits on bobbins and the pressure becomes too much for the alloy hub and it deforms. Some discs are designed to have a bit of float (Brembo) but most dont.
When fitting your new discs some things need to be taken into account. It is important to make sure you use new brake pads as your old ones will be worn to the shape of the old discs and they will not give 100% contact with the new disc. Also, the calipers need to be in good order with nice free moving pistons and if your bike has sliding calipers these need to be free moving also.
Something many people dont think about it the surface the disc is to be mounted to. Corrosion can build up in this area and it is important to clean it up before you install your new discs otherwise you are not mounting them to a flat surface, even a small amount of corrosion can cause problems.
New EBC discs need to be run in for a couple of hundred miles.

EBC X Series Motorcycle Discs

Over the last year or so EBC have been supplying their new X and XC discs as a replacement for the old pro-lites. As the stocks of pro-lites runs down they are replaced with the new design. Pretty much eveyrthing now will be supplied in the new style.
The new design has 2 major improvements over the old ones in that they are much lighter and they have the new square drive button design which not only allows the use of less mounting points for the outer rotor but it also reduces the pressure placed on the alloy hub when braking so these discs will last much longer than any stock set of discs.
As always EBC use stainless steel rotors and anodised alloy bubs.
The new disc is available in a round style (X) and wavy contour style (XC)

EBC Discs

Over the past year or so EBC have been phasing out the old birdswing pattern on their pro lite discs in favour of a universal pattern. The main reason they are doing this is so that the discs will no longer be sided left and right. One improvement over the old discs is the new square drive system for mounting the stainless rotors to the hubs. This clever new system rivetts the 2 parts together increasing the life of the disc significantly, the flat side of the rivett spreading the load when braking which greatly reduces wear to the alloy hub. Another benefit of the new design means that EBC have been able to reduce the number of rivetts that hold the rotor to the hub reducing weight which in turn benefits the handling of the bike by reducing unsprung weight. Well done EBC.
