Dealer quoted 5k for brakes – worth going to an expert instead?

My 2019 540i is due for front pads and rotors plus a brake fluid flush, and the dealership just hit me with a 5,000 AED estimate which seems absolutely insane for a job that takes maybe two hours. I know these cars have electronic parking brakes that need a scan tool to retract the pistons, so I'm not comfortable taking it to any random garage, but I've been reading about independent places that offer Expert BMW Maintenance Abu Dhabi without the crazy dealer markup. Has anyone here gone the independent route for brake work and been happy with the results? I'm worried about aftermarket parts squeaking or wearing too fast, but paying 5k feels like robbery when the same OEM parts cost around 1500 online. Would love to hear real experiences before I either empty my wallet or make a mistake I regret later.

Electronic parking brake retraction on the G30 540i needs proper diagnostic software, but any genuine BMW specialist will have that capability without charging dealer level prices for the actual brake job itself.

5,000 AED for a two hour job when the OEM parts cost around 1,500 online shows exactly how much of that quote is pure markup rather than reflecting actual labor or part costs.

Quality aftermarket pads from reputable brands perform identically to OEM on a daily driven 540i. The squeaking and premature wear concern only applies to unknown budget brands, not all aftermarket options.

Had my G30's brakes done at an independent BMW specialist last year using genuine parts. Half the dealer price, no warning lights, EPB worked perfectly, and the pedal feel was identical to before. No regrets going that route.

Ask any independent shop directly if they have the proper EPB scan tool before booking. A confident yes with experience on G30 platforms means they have done this exact job many times and know precisely what they are doing.
