My new old '88 truck needs a new brake light switch. It's got a release switch thing for cruise control in front of it (but no cruise control on the column), and I'm wondering if anyone with a similar set up can give me some basic tips on how to get to that brake light switch, in order to take it out. Can you wiggle your fingers around in there and get it loose, or will I have to take something off to get to it? The cruise control switch is on the brass bracket from the steering column. Even if I take the cruise control switch out, it's hard to get to the brake light switch. But I'm new at this, so maybe I'm whining too early or missing something.
Im wondering what issue would cause the rear wheel cylinder ears that hold the brake pads, to shear off? I have a 2006 GMC Sierra 1500 2WD 4.8L with rear drumbrakes.
I replaced the rear wheel cylinders and brake shoes on both sides. After 5-10 minuets of driving, i had extremely loud squealing from the rear when braking to a stop. I took off the drums to check and saw that the passenger side wheel cylinder ears had sheared right off, but only on the outside of the truck, not inside ears. The shoe that is towards the front of the truck also was pushed out towards the inside of the drum and was rubbing on the inside facing where the hub sits so that must be what was causing the squealing. But i dont understand what would cause such a force to shear the wheel cylinder ears right off. Drum out of round? Before i replaced the shoes, both passenger and driver side shoes towards the front were almost to the metal shoe backing plate, so thats why i replaced them.
2015 Silverado 1500
This weekend I changed my rear rotors. It was a simple swap, old ones off, new ones on. The next morning I went to start the truck and barely got it to turn over and the DIC threw a message up saying service trailer brake system. My radio also completely reset and when I press on my brakes all lights dim. Any suggestions in what this could be?

I have a 2000 Silverado 2500 6.0l. Long story short, I was bad and shotgunned parts at it. Replaced Hydroboost, master cylinder, and the power steering pump. Also put in a new return line from hydro boost to pump with an inline filter. I still have no power steering, and the brake pedal goes to the floor and slowly comes back up. I’m lost.
Apologies in advance for any poor forum posting, I’m new on here.
Got an interesting one for the forum. After the truck (2016 GMC Sierra) has been sitting a while (usually over night or for a few hours) the pedal let's out a nice squeak. On rare occasions I can get it to do it twice in a row, but most of the time the squeak is only for the first press then is gone for all the other presses. Normal daily driving I don't hear it, it's only the first press or when I have to hit my brakes hard (ex, cut off by someone). My local dealer service department (who's treated me well and has good mechanics) looked at it and said they can't repeat it enough to truly diagnose it. Some squeaks are real quick and others last about 2 seconds. The only way I can describe it is like a relief valve letting some air out, but with a squeak. Sometimes I can hold the pedal in place after depressing and the squeak continues to let out. It's not like a metal plunger rubbing on a rubber boot as I depress the pedal, plus I would be able to make the sound every time if that were the case.
Below is a video I took on two different occasions, they are looped a couple times. You'll hear what I'm talking about and see that it's gone on the second press. I did have the vacuum pump replaced due to the recall about a year ago, I noticed it after that but the dealership said the pump and vacuum is holding well the entire time, even when it squeaks. They only guess they had was to replace the brake pedal assembly or the brake booster, but admittedly said that would just be throwing parts at it. Just got the truck back today, didn't get charged for the diagnosis since they couldn't figure it out. Now I'm turning to the forum. Any idea what's going on?!?
