if your talking about the switch that tells when your foot is pressing in the break yea just get under there and there should be a button switch with a nut you back off then remove the switch out of the brace.

in park idling

SOURCE: Yellow DSC and Brake light on... recently changed brake pads

Abs and dsc are related and with the light on these won't work. It is possible that you need to go back to where the work was done to look this over.

oh dear, this is going to be very bad new for you,take it from me the ATM fluid is leaking out of your gearbox, it could be a rear gearbox oil seal, it could be the front gear box oil seal leaking, even the oil cooler or pipes leaking but it is leaking some were, and if its got to be took out to put in a new seal your going to need to sell a kidney or some outher part of you to pay for it, if you can put up with the leak just keep filling up your ATF fluid dont let the gearbox run dry or its realy going to cost you, as it will seize up on you and burn its self out, thats a new gear box then??? costly very costly! if its only a little bit of oil leaking give the motor a good wash down with a power hose under it and fill the atf up go for a drive say 10 miles then look under it, look for fresh oil (ie:red oil) around the gearbox at both ends of it, if you see any that is proof its leaking bad!!! park it over a sheet of paper over night will show how much it leaks too, i would put up with it as long as pos bet if its due for an MOT give it a realy good power wash down first to get rid of any oil, a little leak will still pass, a big un, wont! any oil seal can just fail on you like this one has but they fail much faster if they get over heated due to lack of oil in them
sorry for the bad news, think of selling the kids to pay for a new gearbox,, now there's an idear?
