RX3 Aftermarket: Front Brake Calipers, Rotors, and Brake Pads

[peperino]

My country is awful to buy things outside of it, we are limited by 2 items/year and it is very tedious to pass customs, so I would like to avoid having to replace the rotor. A better brake pads would work? Or mabe send the rotor to have it fixed?

As of this moment, I don't know of any other brake pads which fit the front brake caliper.

I suggest you contact the seller, and tell him of your problems. You can refer him to this website, where we discuss this problem. Replacing the front brake rotor will fix the problem. Therefore, I suggest you ask the vendor to send you a new, front brake rotor under warranty coverage.

Im out of warranty, as here they enforce you to do periodic mantenance services with them, otherwise you are not covered. As I had horrible experiences with official service shops, I made all my maintenance myself, losing the warranty in the process

Sad to hear that peperino.
Wouldn't be easy for us to explain at our North American fellows the local situation involving aftermarket services for motorcycles, cars, trucks... specially after reading the unbelieveable -for us- experiences that many of them had with the excellent responses and attitudes of CSC with their customers.

Would be nice if you can pinpoint the trouble to the rotor disc, measuring its thickness on 7-8 points.
Found this video that maybe can help you:
Methods 1 and 2 are fine; I wouldn't consider the 3rd.

I'm going to measure it. Do you think a different value would indicate warping? If so, could it be fixed?

[ElectricCircus]

A different value indicates unevenness of the Surface; the best solution would be to replace the brake rotor, but at our countries many times is more affordable or available a hand-made solution, like rectify or polishing.

If the rotor is flat, the failure is elsewhere: bad rotor seating/improper bolting to the wheel, misaligned caliper.

Where you feel the issue at breaking? Both on the handlebar and brake lever?

[peperino]

The issue is uneven breaking performance, like a pseudo ABS xD
Very annoying when you want to go a full stop, if you missed the 'good' braking part of the wheel rotation the bike will not stop the same as with the good, forcing you to apply more pressure which, in turn, will make you brake HARD when it reaches the good portion. I hope I said that right

[ElectricCircus]

I've sent you a private message: would be easy to go further by means of a phone call

It may be that your warranty requirements are different, but there is no periodic maintenance required for a rotor, so even if your dealer did the maintenance your problem would still exist. This is a manufacturing defect and is unaffected by maintenance.

I agree completely.

That's correct. But it is simple, no services done in official shop, no warranty claims. That's how it works here :(

Welcome; we are glad you joined us.

Thanks for confirming the front brake pads. I see the Kyoto S1098 brake pads are equivalent to EBC FA185, which fit many Honda dirt bikes, including my Honda CRF250X and Honda XR650L motorcycles.

I wonder if a spring from a Honda, front brake caliper would fit the RX3, front brake caliper? I am going to try installing the front brake spring, and the front brake pads from one of my Honda bikes into the RX3, front brake caliper.

Will definitely await to see what you discover....thanks Spud
