Brake not working consistently after startup.

[oscarach]

I am having an issue where sometimes when I start the Gladiator, put it in drive and release the parking brake the foot brake will not hold the vehicle stationary have to hold it with the parking brake if you can’t move off immediately. The pedal feels about the same as normal , but it’s like there is less braking force. Then when you actually move off and try the brakes they work fine and will hold the vehicle fine next time you stop. Only happened a couple of times. Although I did also have one time where about 5 minutes after starting the vehicle I missed a turn as the brakes felt like they had less than 50 of their normal stopping power and the pedal was a bit spongy, then everything worked as normal again after braking hard a couple of times.

I am going to call the dealer tomorrow but just wondering if anyone has seen anything like this.
Wheels and tires are still stock so not trying to top any extra weight.

Might have a master cylinder going bad

Might be air in the lines.

Park it.
Get it towed to your dealer.
Inconsistent brake power is a loss of control.
Your rolling the dice by driving it.
Is it worth it to chance it will work when you really need full braking power?

Turns out this nut was missing from the brake booster. Dealer replaced it and all is working properly now.

Just wondering, is there a paint pen inspection mark on the other side nut?
