Have had my Giant XTC 4.5 for a year now, and it has been performing fine for me.
However I recently washed it for the 1st time ever (using washing up liquid – with hindsight I realise I should maybe not have used that??)
Now when I am riding my front brake is not as sharp or snappy on braking – it used to be before I washed – it kind of ‘fades’ a bit now and doesnt stop on a dime like they used to :/
I think the problem maybe either be that I have got soapy water the front disc so its maybe *too* clean? The guy in the bike shop said that going out and getting it a bit muddy can work wonders, is that true?
Also I may have got soapy water into the pads which may have affected their performance? :/
Is there anyway I can rectifiy this without buying new pads etc? Any adjustments I can do? Could it be a brake fluid problem?
A lot of questions I know – Im a newbie to all of this caper so all help is welcome 😀

Clean both the pads and the disc with meths, as a starter. 8)

haha… i think he meant that the discs may be too clean and a bit of dirt etc on them might help to make them more ‘grippy’ or something? does that make sense or is he talking £$*%! ?
ill go get some meths and give them a clean with that – is it just normal meth spirit that I can get from any hardware store?

Yes, looks kinda purple/blue-ish in colour. Dries instantly, smells nice but only tastes nice with vodka …… (only joking!)
If that doesn’t work, I’d just spin the discs and hold a bit of 600-grit abrasive paper against them, in case the soap has glazed them up.
Ask the bloke at the shop if his mum rinses the dishes in mud to remove the Fairy Liquid residue.

haha yeh ill drop in and suggest that to him 🙂
i also read that IPA is better than Meths for cleaning discs, as the IPA doesnt have any additives or something… or is meths just as good at doing it?

Dirt and water on the disc and do hard braking from a reasonable speed to get the pads back to life.
I think Magura advise 30 stops from 30kmh to bed pads in initially.
You need to avoid getting cleaning products on the discs and pads really.

to bed pads in initially
But we’re talking about loss of performance after washing with Fairy Liquid here, aren’t we?
Tom, why avoid cleaning products?

I had a similar problem with my 4.5 but thik i mis-directed the teflon lube straw onto the pad 😳
i used Muc-Off Disc brake cleaner on pads and discs which worked wonders
