Do I Need New Brakes?

Lately they have been squeaky. Whenever its humid out or it rains, then first minute or so I am driving it the brake is super sensitive and its like I have to warm them up. My truck as been sitting a couple days in the rain and humidity and just now I went from the street to the driveway. I was literally going 5 mph, barely tapped the break and it grabbed on like I had just put all my force onto it.

 

There is no grinding or anything. I have no idea how old the current brakes are as I bought the truck used. I am about to hit 60k miles though.

It sounds pretty normal. Mine get a slight coating of rust on the rotors from sitting for even a few days in the rain and humdity. The grab you are feeling is probably just the rust wearing off.

 

Having said that, may be a good time to check them. I got about 70,000 miles out of mine, I bought the truck with 15,000 miles on it, and am pretty sure they were not replaced when I bought it.

If you bought the truck new and have never had the breaks changed then do your self a favor and get them checked. The factory breaks seem to be either hit or miss, for me it's a miss but for others their fine.

My 2010 when new...would squeak every now and then after sitting when backing out My driveway. Asked the dealer about it and they claimed it was rust. OK...that's fine, but what kind of product rusts immediately after sitting a day or two ? None of My other trucks did...Fords and dodges...even My 97 silverado. I guess it's another "use or lose" due to cost cuts...cheap metal.

My 2011 does it once in a while when it's humid or has rained and sat for a while. :thumbs: Sounds normal to me.

All brake rotors rust if they are sitting. If you notice, when you purchase new rotors they have a coating of lube on them that should be cleaned off prior to install. The lube is there so the rotors do not rust in the box. You probably just did not notice as much on your other trucks but they do get rusty from sitting.

      Thank You Another JR, I watched the transmission temp the highest was 214, the engine temp seemed normal.  Hoping not a valve body issue, but...

      HighMileage oils or stay with Dexos 1 ?

      By Z45 · Posted

      dexos began as an effort for GM to control the oil change market because the Quick Lube Industry was eating into dealer service department profits big time. So they attempted to get other oem’s to develop standards as well and that would make it hard for Quick Lubes to compete because all the oems would be different. GM faced lot of industry push-back, mostly the quick-lube industry and they went to licenses. Still GM it making a ton of money (est'd 30-40 million in 2025) off the license structure as they charge a hefty fee to get oil tested then require a royalty on ALL gallons sold applicable to GM vehicles.

      Those are parts changers. It can get expensive though. I was a mechanic for 30 yrs. My truck has made this noise since new. I really don`t know what it is. It really doesn`t bother me. I`m still in warranty but have not brought it to the dealer.   I`m not buying the oil pump prime thing. Screw the TSB. I believe it`s in the trans pump gears. They rattle when that piss poor ULV oil drains off after a while. I believe those sharp tooth gears, with backlash, can rattle when dry. Not a vane style oil pump. Wonder who`s right? Me, or the TSB?🤔   Maybe I`m wrong?

      Wow I'm in a pickle. (Broke down truck) and a story.

      On the PCM side, blue PCM connector, pin 18, solid gray color (no stripe) wire circuit 435.  That is the EGR low circuit which an issue on that line (be it the wiring, the PCM or the EGR valve or system performance) will trigger P0401 when it tests that code.     There is also a VERY old TSB that states to make sure you clear the DTCs ANY time the PCM is unplugged, reprogrammed, or if the EGR valve is unplugged or replaced as the PCM has an auto zero function in the PCM for the EGR pintle data   61-65-59: SMU - SECTION 6E - ENGINE CONTROLS - CLEAR DTC'S - (Nov 25, 1996)   "CLEAR ANY DTCS FROM THE VCM ANYTIME AFTER DOING VCM REPLACEMENT/ PROGRAMMING, TURNING THE IGNITION ON WHILE THE EGR VALVE IS DISCONNECTED, OR REPLACING THE EGR VALVE."   Some diagnostic aid notes in the GM diag on P0401 for a 1995 S10 Blazer:   Diagnostic Aids Notice: In order to prevent further damage if the EGR valve shows signs of excessive heat, check the exhaust system for blockage (possibly a plugged converter) using the procedure found on the restricted exhaust system check. If the exhaust system is restricted, repair the cause; one of which might be an injector which is open due to one of the following reasons: Stuck Grounded driver circuit Check the oil for possible fuel contamination if a stuck open fuel injector is found. Poor connection or damaged harness - Inspect VCM harness connectors for the following conditions: Backed out terminal BL 18 Improper mating Broken locks Improperly formed or damaged terminal Poor terminal to wire connection Damaged harness Intermittent test - If connections and harness check OK, monitor a digital voltmeter connected between terminal BL 18 and ground while moving related connectors and wiring harness. If the failure is induced, the voltage reading will change.
