Exactly why I don't use brake cleaners, they always leave a film on the rotor and pads in my experience, never get them back to 100%.
Aren't they supposed to be the best thing for pads?

Yep, need some pad build up on the rotor

Hi,
I want to perform a quick service on a Fox 36 FIT4 and a DPX2 : lubrification only. About oil :
*Fox 20wt gold is required for the fork, not so expensive (18€/L)
*fox float fluid (blue oil) for the shock, uber expensive (80€/L)

Is there any equivalent to the fox float fluid ? read alsewhere that synthetic gear oil could work (85W90) or Torco MPZ (never heard of this)

Also on RS suspension they recommend grease instead of oil on the seals, would that work on fox (RSP Slick Kick for example) ?

Remembering that some oils do not interact well with seals of some makes.

For example Maxima as used in RS with DVO.

Just a headsup that this might be the case.

Get some wet and really gritty dirt, plaster it over your rotors, pedal down the road and do a bedding in type process, the abrasiveness grinds all the contaminant away, it sounds horrible when you are doing it but that loud grinding sound is a good sound.
Have just done it but much better but not good yet

Is there such thing about too steep of a hill to bed in brakes?

Theres a super steep hill local to me that is about 250m in length with a 50m elevation drop, and I was thinking it would be a good place to get speed to bed them in. And (if that is fine for the brakes) about how many runs of that should I do to fully bed them in?

I'd probably get someone to shuttle me up every time, so going back up isn't much of an issue

You don't need high speeds to bed in brakes. Just a few sprint/brake stops and a few coast/brake stops.

I'm not sure about the dpx2 but the float seal kit comes with a pillow pack of the blue...

Unsure if the dpx2 uses the same kit as a float but the float kits include a pillow pack of the the blue if that helps...

don't completely stop when bedding in new brakes and rotors.

My tubeless tire is leaking from two nipples. Can I just toss some glue on the nipples, or do I have to retape the whole thing?

It'll be better in the long run if you just retape.

But first, make sure your valve stem is tight, its usually not the fix, but once in a while it can be.

Yeah, that's what I was thinking. It's definitely the nipples, I sprayed soapy water all over the rim/tire to find the leak and there are 2 nipples that have bubbles. Unless this is somehow related to the valve stem?

If the air finds a hole in the tape it will push sealant out at the easiest spot on the rim, usually at a nipple. Usually if the valve is leaking it bubbles there but not always. Its worth tightening to make sure.

This ^^

You don't want to over heat the pads doing a big steep hill for bedding, like seraph says, few sprints and stops on the flat/gentle slope is ideal, sprint stop on one brake a few tiems till it works, then the same with the other.
