Front brakes dragging 2006

Greetings all! Sorry if this is redundant but I've searched other posts and could not find an answer.

The front brakes are dragging on my '06 Double Cab Limited, specifically the right front. I have replaced both calipers, rotors, and pads but the problem seems to persist. I only notice it when travelling at highway speeds. The truck feels sluggish and when I lightly tap the brakes they immediately respond as if the are already partially activated. After tapping the brake pedal, it returns to normal until I have to brake again. Could this be faulty brake lines? I have read in other threads about the inside of rubber lines breaking apart and possibly causing the fluid not to release back into the system. I can't imagine what else it could be. Thanks in advance for your help!

 

An incorrectly adjust master cylinder can also cause this. But not likely unless you replaced it recently and it wasn't installed correctly.

 

Did you happen to bleed the brakes BEFORE you installed new calipers? I've heard it's best to do this so you aren't pushing old gunky fluid into brand new calipers. I'm just wondering if you have some debris in there making the new brake pistons stick. Seems less likely though. Google does say a worn out brake hose can cause this but I've never heard of this. Might be worth upgrading to stainless steel hoses which many of have done.

 

I bled them after installing but made sure I pushed new fluid thru them before actually driving on them. Where does one get stainless steel lines?

 

These are what I ordered but there are other options out there.

 

This was going to be my suggestion as well. Stainless lines make a very big difference with braking. Does the OP have ABS on the truck?

 

I agree with all the posts about bad brake soft lines. Especially if you were to pinch them shut during the caliper change. The hoses can act like a check valve and let fluid in the calipers but not let the fluid back out. I haven't tried the stainless lines myself but if you don't want to spend as much the rubber ones seem just fine and that's what I did recently on my truck.
