I have a clicking from my rear wheel (sometimes in the front too), when applying my brakes. Sounds similar to a aluminum can tab being snapped, or can being flexed.
I have tried re-torqueing my rotors (40Nm), Brake calipers [Mount to frame] (8Nm), cleaning the pistons, pad spring and pads using iso 99%.
I have also tried cleaning where the spokes make contact both to the hub and with each other incase any grit from the beginning of the year.
There is movement in the spider of the rotor, however I would expect a little movement as it is a floating rotor design (space allowed between the rotor, rivet and spider for thermal expansion - at least I think).
I have also tried putting masking tape on either end of the pads as there was some room for the pads to move and I wasn't sure as the pad was being modulated if it was rattling in the caliper.
I have a couple of more attempts to identify the cause:
- Switch the front and rear rotor to see if the noise moves to the front wheel
- Switch the wheelset to my older one with different rotors.
- Use the rotors from my old wheelset
- Use my old resin pads with the current wheel set.
- Give up and take it to the LBS.
Before I go further down this rabbit hole, I was wondering if anyone else has any ideas or experience in a similar problem?
Pad wear is at more than 50% left. The noise occurred maybe 2 weeks after they were installed.
