2016 Mustang GT Advancetrac issues

[Ronfrank1]

Looked all over this page and found similar problems so here goes... bought the car in January 2019, with 38000 miles, drove it with no issues what so ever now it has 56000 and the Service Advancetrac, hill assist not available and two traction control lights come up on the dash and I have no power steering. Took it to the dealership and they said “it’s because my tires aren’t factory size (275 instead of 255). After I got it back from them everything worked perfectly, but a week later it all happened again. I haven’t done nothing mechanically wise besides change master cylinder and brake booster cause they were leaking INSIDE my car out of the clutch... (it still leaks) so that still a problem... and I just changed the ABS Wheel Speed sensors today with no luck. Any confirmation on the tires thing or help with the leak would be awesome!

I'm no rancher, but the tire thing sounds like bullshit to me. I also don't know much about hydraulic clutches, But I'd venture a guess that you need to fix that leak then a major brake bleeding. My understanding of traction control is that is uses subtle targeted braking to control the vehicle. Hopefully the M6 gearheads will chime in.

I would say there’s a direct link between your brake issues and the traction light.

The tire thing is BS as @lacanteen mentioned.

Brakes and everything worked fine just leaks but like you said I think it’s linked to it as well... just gotta figure out how to stop the leak!

Here ya go, this is probably your issue (seems to be a common one across the S550 platform too):

Read that whole thread going to check out that ring and which one is busted I guess replace the bearing and ring itself and hope that it going away! I let y’all know what I find thanks again

This is where the brake fluid is leaking out of

Did you change the clutch master or the brake master?

My understanding was they were the same thing but I changed the brake master cylinder

 

[Ronfrank1]

Never thought the noise I was hearing from the back was a big deal but after doing some more research my bearings sound like they are going out so I’ll replace those and let y’all know how that goes!

No. There is a clutch also...

Yeah I read the same thing shoved it down as far as it’ll go when I replaced the master cylinder and booster but still leaks. I’ll look at it again and see if it came off or something

It’s for sure shoved all the way on the cylinder price but does look a little off I’ll redo it when I get my hands on some dot 4

I purchased the steeds upgrade and changed both rear hub assemblies and advancetrac + still on... any different ideas? I think the leak has stopped though
