Indy has the thickest pants ever! As said, line brus with and/or diluted conditioner. I use 4 tools all with a line brush technique
I start with the slicker mainly to to loosen things up
The move to the rake. Be careful about the kind of rake you choose. Teflon coated, no sharp points or edges, medium spacing
The I slicker. And finish with the pin brush. My favourite is a 35 mm. The only I know that sells this length is Chris Christenson. It really gets in there. It's the only one I use
I use the comb to deal with individual problems spots. Eg. Big tangles.
And always brush with a spray bottle. You want to mist....not saturate.
