i have a 99 dodge ram 1500 just did the rear drum brakes. got in the truck to check the brakes, pumped a few times, pedal went to the floor and the abs and brake lights both came on. plenty of fluid in master cylinder didn't see any bad lines or leaks abs sensor is only a couple of months old don't understand why pedal is going to the floor and those lights came on. any help would be appreciated.

 

I think you should pull both drums again and inspect everything . My guess is one of those small pins came out of position on the brake cylinder or you need to tighten up the adjusters a lot more .

 

You did put the drums back on before pumping the brakes, correct?

 

Yep the drums were put back on before I pumped the brakes.

 

Had to ask. I had a do'h moment one time doing my rear brakes and forgot to put the drum back on. Makes quite a mess. Lol
