2010 2wd rear disc brakes pulsing

[mustlx90]

Hello all,
A while back I replaced the rear pads on the truck. A few months later I started to get a pulsing in the pedal. I assumed it was the front brakes turn. Due to a lack of time I had my mechanic friend change them. He put new pads and rotors on the front and started to drive the truck around the front of his shop and noticed the pulse still there. He put the truck back on the lift and replaced the rear pads I put on (which still looked new) and put new rotors on. He said he'd never seen rear brakes on any vehicle cause a pulse like that before. I remembered that weird e-brake setup it had, I hoped I didn't mess something up.
Anyway, fast forward to now. Just about a year later and the pulse is back again. I hope I don't have to replace the pads on this every year now. If anybody else has experienced this and figured out a cure, I would deeply appreciate it.

Brakes can be a tricky thing, pulsing usually means they got warped going through water when hot. Since your truck is newer than mine, the problem could also be with the ABS. That's just a guess, but its something you might want to consider. I'm only giving you an idea on what to look for. The upside of this is, eventually, someone on this site will have the answer to your problem, and I'd bet its going to be something simple. Welcome to the club.

Hi,
thanks for your input. You mentioned going through water. One thing I forgot to mention is that I did drive home in the pouring rain a last week, and the pulsing went away 99%
If my buddy didn't just changed the rotors when he did, I would lean more that way. It may just come down to jacking it up and pulling the wheels off again. He actually saved me all the old parts. It may just come down to that warped rotor. I still bothers me that I had no problems until I changed those pads the first time.
Thanks for the welcome. I'm glad I made it 11 years before I needed to look for help. When I had my old Dakota I had to lean on the Dakota forum a little more. - No gripes with either.
