Title: New brake discs??
Post by: fbenach on July 29, 2015, 01:33:00 AM

Hello everyone!!
I tried to do a search on the "replacing for something better" matter on the brake discs, but couldn´t find something, so here it goes:

In the past I discussed with some of the gurus here the fact that original discs (I have double discs over ATE calipers) tend to lose their braking capabilities when wet, seemed everyone agreed on the matter.
Now, I do want (and need) to replace my old discs and was wondering if theres any other good option besides the original discs, which will have the same "wet problem".

Any thoughts? I´m kinda lost, and by looking at the prices (don´t get me wrong, last thing I want to do is saving money on brakes!!), I just want to do a smart investment here!!!

Again, thank you all for your wisdom!!!

Cheers,
Fernando

I replaced both discs on my '81 R65 with EBC steel rotors and EBC, I believe FA57 pads, for ATE calipers .
I saw an increase in wet braking capability.
I live in a desert, so riding in rain isn't too often .
Before the parts replacement I wouldn't ride if wet conditions were forecast, now I have no real concern about riding in rainy/ wet conditions .
I've heard from some members, the EBC steel rotors will rust, I have not seen that yet, in 8 years .

The EBC rotors are a good replacement - I don't recall if one has to come up with different length bolts for them or the original ones will work to attach them?


I found that my stock BMW stainless rotors on my 82 R65LS worked much better in all conditions after putting on a new set of EBC FA18 organic pads (these are with Brembo calipers, though)

Doesn't the EBC discs with the floating rotors rattle?
I've been looking to replace mine with those also.

My Triumph Trophy has twin disc brakes up front. Four pot calipers each side with floating brake rotors. The rotors are quite solidly mounted. The floating brake rotor design and description can often be misleading. Both of the Triumph's rotors are solidly attached. No rattles. However, those amazing carbon brake rotors on those MotoGP bikes are true "floaters".

Here's some information regarding floating brake rotors from the EBC website:
