So I need your help on this. I’m going to a different dealership because the first one sucks. I’ve had this issue for quite sometime. It’s annoying but does not affect my braking. However, I would like it fixed. My first dealer has no idea what’s causing it so they won’t/can’t fix. Can someone give me an idea or have had this issue before? Thanks

Wow that's a very shitty dealer service department if they can't diagnose that.  Get it to another dealer.

You’re telling me. I drove with the senior tech, manager, service writer and they still couldn’t fix it. They gave me the same bs that once they pull it around they can’t duplicate it. However, I duplicated it every single test drive with them. And trust me it was multiple times. I have soo many videos of it as well. Happens everytime I’m in the truck. Especially, going downhill and slight application to the pedal. I could do it while parked as well. I just want to know what it is. I would fix it if someone could point out the problem.

These trucks essentially have a brake-by-wire system (ZF IBC). That noise sure sounds like it’s emanating from the very complex and expensive master cylinder. Need a competent dealer unfortunately.

Abs while parked? I’m also barely applying pressure to the brakes when it happens.

Mine does the exact same thing if I barely touch the pedal.  Like said above, it's the electronically-controlled master cylinder and ABS module.

Thanks guys. Now I have something to go with. Lapoolboy, it doesn’t drive you crazy? Mine does it all the time

    • I remember watching one of the auctions on TV. It just happened that they had two little red express trucks. My brother bought one new in 1979, still has it. So I hung on to watch them cross. The retro redone example brought more bids and went for more money than the original one did. My brother has redone his 3 times and raced it. He’s now in the process of making more tame for cruising. 
    • I always upgraded the suspension and steering components - bushings and ball joints, and had older cars that I could out-corner ANY modern car with. I used to be able to take my '78 Cutlass on off-ramps at stupid speeds and make the sharp MA corners without even squealing the tires. So much fun. My '72 El Camino must've had work done by the previous owner, since that thing seemed to handle even better than the '78.   I think the suspension & steering on the '72 was much more advanced than the '64, so that probably just made a good system even better.   I'm the same way with vehicles. I hate having to worry about the paint on my '93 W250 Cummins. I'm not used to that, lol.   https://postimg.cc/mzKr55sY
    • BEAUTIFUL!! That a Cutlass F85? Or 442? My side-ID skills are lacking thanks to failing memory, lol. Love that color & year, too!   Yeah I was never big on entering my own stuff, but I always liked seeing what everyone had, the rare models, and what's been modified. That was always fun. These days I have barely enough time to do what needs to be done at home.    Oddly enough, here in MA there are more car shows than ever in history! You'd think up here it would be dead, but it's bigger than EVER!          Took the 940 for its maiden voyage with the carburetor. At first I couldn't get out of the yard! This originally had the "Bosch" system (our other 940 has Regina - single fuel pump in fuel tank, and space-age-looking ignition coil on driver's fender) - that has dual fuel pumps. One in the tank, and one under the center left of the vehicle. I had unplugged the external one thinking I wouldn't need it with the carburetor ... but the way I have the pressure regulator hooked up, 90% of the fuel volume is going back to the fuel tank, so cranked all the way down, the regulator is only supplying a hair above 3.5 PSI to the carb. Turns out the in-tank pump (15 PSI alone, instead of 45) couldn't handle the load. Plugged it back in and went for a rip. Ran great!   Throttle response is always amazing with carburetors. ZERO delay that no FI system can reproduce. Also fires up in half the crank rotations as before. Low end power was DRAMATICALLY improved. There was an ongoing lean issue with the FI that I got tired of figuring out, so this is a MASSIVE improvement! Above 50 MPH on hills it feels SUPER weak, though. This is more than likely due to the timing not being advanced enough by the computer, since it believes there are multiple failures. I can live with that through the winter. Will keep me from passing slowpokes where I shouldn't and getting speeding tickets at least. 😁
    • I like driver quality. I bought a 64 elcamino a few years ago. All original as it turned out. I didn’t know at the time. I made a low ball offer and got it. Black on black factory air 4 speed. It drove like a school bus. It had been awhile I had forgotten just how bad the old cars drove. So I planned on making it more of a retro ride. I would drive it to work sometimes. My brother liked to build cars, I liked to drive them race them. So he noticed the canister oil filter and open blow by tube. He checked the numbers. All original. 327, 250 hp close 4 speed, posi rear end. I put it on eBay made a tidy profit. I didn’t want the responsibility or headache. My wife already had a pristine collector vehicle. It lives in the climate controlled garage. I really don’t care what it is. I like to feel the sensation of speed. Let someone else have the responsibility. I’m too OCD. It used to drive me crazy. I can appreciate people who like to take the responsibility. I’m glad they do. I’ll look and remember back to those days. I’ll jump in the wife’s Genesis to get gas for her. Get my sensation of speed and be happy for awhile.
