SCT Tunes causing rear brake lockups??

[madcat6183]

I hope this is the right section, but here goes;

I got new brake pads/rotors done in Nov. and had some catching issues on the drivers side but that worked its way out, no one could tell me what was wrong, but it went away.

Anyways; I got an SCT X3 and custom tunes and put it on Economy, but after I put the tunes on my passengerside rear brakes were really locking up, I mean like I would get on the pedal and I could feel the brake grabbing. It seemed that anytime I stopped and turned off the truck it woulds tart over, but it's gotten bad. I drive mainly highway so this is eating through my brake pads.

My mechanic is taking my truck this week to do the EGR delete and Gauges, so I told him about this and he is going to look into it, but I m looking for ideas.

The truck has 100k on it, and original calipers, I m thinking they just need lubed, but Im wondering if they will be needed replaced?

Thanks

Calipers are seized up. Replace em. Tuning has no effect on the braking in these trucks

Time for a brake job! Totally unrelated to the SCT.

Both of the posts above are correct.

Thanks I figured as much. I just had the rotors and pads replaced. So most likely just need new calipers now too. Sweet lol.

Thanks everyone, I kinda figured as much, but wanted to double check.

you can get remans with a lifetime warranty from autozone or advance for $49. I just did both of mine b.c my drivers side caliper locked up on my driving home a couple weeks ago. i have 140k on my truck. Doesn't take long to swap the calipers out and it seems to be a common problem. i woudl go ahead and do both of them and be done with it

Thanks for your help Jeffro, I was curious if I would have to order from Ford, or if they stocked them somewhere.

My truck goes to my mechanic tomorrow night til Saturday for the EGR full delete, gauges/pod, and now rear brake calipers.

Naw man it's the SCT. You have to make sure you have the perfect tune or.........well in MY case it took off the rubber of two sets of tires over 100k miles -- and I rotated them.

Just kidding - the guys are right.
