I took my Silverado through some mud the other day and I have to say the 4x4 is great. I was not able to clean immediately, and two days later after finally getting around to it there is a high pitched squeak from the front right and rear tire. When brakes are applied, nothing. From 2mph to 30 it is audible and loud, especially when turning left.

I've sprayed the wheels down and bought some brake grease. Before I take the calipers off in the next couple days I wanted to ask if anyone had this issue before. Any tips or advice would be appreciated. I am unfamiliar with the regenerative braking system. I'm going to remember to clean it sooner next time...

Is that a bug deflector?

Truck looks beautiful btw, no idea on the brakes tho.

 

Haha. it IS. Can not decide if I like the look of it yet. Certainly does the job because it gets dirty quick. I've kept the truck almost the same since I picked it up. Only changes were taking off some of the stripe work and putting on skid pads underneath.

 

Well I think these trucks have beautiful body lines ... so if it were me I'd toss it.
And since you like to play in the mud, a leveling kit and some beefier tires would soon follow.

Since you're taking the wheels off anyway to go caliper digging, you can do it then.

 

I put a bug guard on mine because the paint on the aluminium hood was getting so many chips in it. Never had paint chip this easily, but I must have 30-40 chips. The guard seems to have helped that situation quite a bit.
