Hi All,
I need help. I want to buy new brakes pads and rotors. What size are the rotors? In MILLIMETER 363MM OR 345 MM

Which calipers do you have, red or plain?

Then you need the bigger rotor.

This^^^^ Street Pack and Track Pack are the same size caliper and rotor, and they come from the factory red. Track Pack pads are different and expensive, but are a bit of a rarity. It's a pretty safe bet you have the Street Pack.

Thank you all for your help. If I remember correctly when I ordered the ST it came with street pack. and towing package. I'm planning on ordering from POWERSTOP.COM Any feed back on POWERSTOP?

I have Powerstop on mine. Just remember to disconnect the battery before installing the rear calipers. That prevents problems with the EPB. Also, you will need a brake kit to spin the pistons in. They go clockwise or right hand rotation

That is incorrect. You put the car into Brake Service Mode and it automatically retracts the rear calipers then when you take it out of that mode it correctly sets the pad gap for the new pads. You don’t unhook the battery and you don’t use any tools to retract anything.

Good catch! You can find the procedure online or here.

That only works when you can actually GET you car into service mode, which no matter what I did (FORScan or the physical procedure) mine would not go into service mode. And my post is not "incorrect", it works just as well.

Physically pushing in the rear pistons can and regularly does damage the calipers. Yes, your way is incorrect. If your car won’t go into Service Mode you need to find out why and have that repaired, not tell people to do something that can damage their car. Not to mention without service mode you have no way to set the correct pad height for the EPB. So yes, your way is certainly incorrect.

Odd, because it works just fine. With NO brake alerts and NO DTC's. The calipers are just like any other caliper that you have to "twist" in to compress it. Yes, you would damage it if you tried to "press" it in. There is a reason that the rear calipers are shaped the way they are and not like the front ones.

Just because you got lucky, and that’s definitely what happened, doesn’t mean anyone should look at this as a proper way to do brakes on this car. I’m not gonna argue with you…you’re wrong and no way you’ll admit it but to anyone else reading this post I would advise you to ask someone that does this stuff for a living what the correct procedure is and why this is a bad idea. I’m sure they’ll tell you to not do it this way. For proper EPB function the rear pad height needs to be set and Service Mode is the only way to properly accomplish that.

There can be such bad info on forums and especially Facebook groups. The service manual is clear on how to go about the procedure.

OK. At the end of all, do I put it service mode or do I use a tool and push caliper in and remove the cap on the brake fluid reservoir? Or do I just take it to ford and pay them to do it for me? Thank you all for you help. :)

Depend on whether you want to take the risk of screwing something up. If you want it done right, do it the right way! Follow the procedure in the service manual. Or, just bring it in.

There is only one RIGHT way to do it and that is to follow the procedure! Other ways MAY work but they MAY not. If you are not sure or comfortable doing it then just bring it in.

I would suggest taking it in. But make sure that your dealer has a good service department or you could use a good certified ASE shop.
