I need some help with my 2020 Navigator. It's got about 65,000 km on it and for the last few months I've been dealing with this annoying shudder when I brake from highway speeds. It's fine around town, but when I'm coming back from Abu Dhabi or driving on the Emirates Road, the whole car shakes when I slow down. I took it to a garage in Al Quoz and they told me the rotors are warped and I need new ones all around. They quoted me around 4,800 which seems like a lot but maybe that's normal for a big heavy car like this? I'm just not sure if I trust them because they didn't really explain anything, just said replace everything. I'm looking for proper Lincoln brake pad replacement experts Dubai who actually understand these big American SUVs and can tell me if I really need rotors or if machining would solve it. The car is mainly used for school runs and family trips so I want it done right but I also don't want to throw money away if it's not necessary. Anyone else had this issue with their Navigator? What did you do and where did you go?

Shudder specifically at highway speed braking that's fine around town is classic rotor warping from heat cycling and the Al Quoz diagnosis is probably correct. The question worth asking is whether machining is viable or if the rotors are already below minimum thickness which determines whether replacement is actually necessary.

The workshop not explaining anything before quoting replacement is a reasonable thing to push back on. Ask them specifically what the rotor thickness measurement is compared to the minimum spec because if there's enough material left machining can fix warping for significantly less than replacement. A workshop confident in their diagnosis will show you those numbers without hesitation.

4800 for all four rotors on a Navigator isn't outrageous given the size of the components but it's worth getting a second quote before committing. Big American SUVs have larger rotors than most European equivalents and the parts cost reflects that. The lack of explanation is the concerning part more than the number itself because understanding why replacement is recommended rather than machining helps you make an informed decision rather than just accepting whatever they suggest. A second opinion from somewhere that actually walks you through the measurements gives you confidence either way.

65000km on a heavy vehicle doing regular highway runs is a reasonable mileage for rotor wear to become an issue. The timing isn't suspicious, the lack of explanation is.

School runs and family trips making you want it done right is exactly the right priority for a brake decision. Getting a second opinion before spending 4800 is sensible not cheap and any honest workshop will understand that. One that gets defensive when you ask for measurements and explanation rather than just approval is one worth walking away from.
