2013 JK Brake problems after Oil Cooler Replacement

549 Views 3 Replies 3 Participants Last post by  surfdogdude
I have a 2013 3.6 JKU Wrangler. I recently replaced the all-too-common problem with the oil cooler. As soon as I got it back on the road, the braked started malfunctioning with dashboard warning lights and a squishy feel.

OK, I replaced the master cylinder, but now that it is back on the road, the brake problem is still the same.

Any ideas or hints are appreciated.
Thanks

The dash was telling you Codes. No codes, is like asking a Taro card reader.

Might want stop replacing parts until you at least know what it is saying is wrong. But a Code that says say 02 bank 1. That could be a wire issue or it could be the O2.

The only think i can think of is that..Maybe you have a vacuum leak installing all the top end parts, could maybe cause the PB to feel soft. You might have knocked something loose, left some not connected.

Codes...

Yup, probably a vacuum leak. You got to pull most of those lines to replace the oil cooler housing.
