MGM-compro has a quite wide range of ESC's with brake => models up to 15s, here's the link for the 10s

Another alternative with brakes are the Schulze ESC's

the fut-xl-32.200WK is a 10s 200A version, the 32.100 is rated at 100A
I have used both brands and both has been smooth w/o cogging, with quite good brakes.
