Dealership said I need to remove Wilwoods and then re-test to see if the errors go away. Typical answer.

What is the Year, make and model and is it a raptor R of the truck in the picture. did any dtc's set when you installed these 6 piston wilwoods. i am interested in knowing because i have a customer with a 2025 Raptor R and another shop had installed wilwood brakes, 6-piston calipers and rotors at the customers request.

im getting

ABS C0021:7A

Brake Booster Performance: Fluid Leak Or Seal Failure

due to excessive fluid present because of the larger brakes, and so is sees a leak. we had an FSE from Ford come to our shop for the same thing happening in a Hennessy Venom F-150 due to larger upgraded calipers, brakes and rotors.

So if by chance you were able to install a front wilwood brake kit on a newer raptor with an EBB i would love to know how you were able to accomplish that. A Wilwood rep told us that a new EBB and re-flash is what has fixed this in other models. I dont know how a 2025 Raptor R with 252 miles would benefit from a new EBB when is already has a brand new EBB and the values inside of the abs module cannot be changed to accommodate the new Wilwood calipers, rotors and brake pads.

I also have a phone call with Wilwood tomorrow as per the customer request because they want to keep their upgraded brakes but want to know without a doubt that they will have to go back to stock for the codes to go away.

Did you ask Wilwood who is paying for that? Obviously OEM warranty doesn’t apply, so it’s either them or the customer. It sounds like during development they verified kit fitment to the truck but compatibility with EBB.

Larger calipers are known to cause that issue due to increased fluid displacement. The dealer cannot diagnose an issue with aftermarket variables involved.
