Most motorcycle problems are caused by the nut that connects the handlebars to the saddle.

Rear Brake Disc

Post by ashcroc on Tue 22 Sep 2015, 9:18 am

My rear disc is a bit warped & needs replacing.  I'll be using EBC HH sintered pads to match the front but not sure which disc to go for.

After a quick look on ebay EBC, brembo & OE honda discs can all be had for around the same price.


Since I trust the quality of all three parts, does it just come down to which one I prefer the looks of?

Hmm I don't remember any wobble on that one. It's worth considering dependant on how much meat is left on it.

Just one thing to check: I thought my disc was warped but it was actually corrosion on the hub where the disc sits that meant it didn't lie quite flat. Might be worth checking before you shell out for a new disc if it's not down to the wear limit.

Also, correct me if I'm wrong but I thought OE Honda = Brembo.

I'll be sure to check when I get the old disc off but I'd still prefer to have a new on to hand if it can't be made straight again.  It's not like it won't need replacing eventually.

While the caliper & OE pads are Brembo, I don't think they bothered with the same manufacturer for the disc.  The Brembo disc I'm considering is definately different.

At the moment I think I'm leaning toward the EBC disc to match the pads.

Yes, I stand corrected, the OEM disc is indeed Sunstar. 


I guess the flip-side of what I said about corrosion is that without checking/correcting that you might install a new disc and still have symptoms of disc warp that are actually caused by the disc not sitting totally perpendicular to the axle.

Yeah.  It's always good practice to make sure the mating surfaces are clean & in good condition.
