2007 Sierra Brake Pads

Hello,

 

I recently purchased a 2007 GMC Sierra extended cab pickup. It has a lot of extras on it since it was my dad's but when I ordered a new set of ACDelco brake pads I didn't realize it had Stabiltrak or RPO JL4. Since I already bought ACDelco p/n 171-0974 can anybody tell me if they will work okay on my truck or should I buy the ACDelco p/n 171-0975 brake pads which their website calls for?

 

The break pads I bought seem to fit okay but the inner pad is a little tight. The existing pads I found have the same situation even though I have cleaned up the cradle and shims of any corrosion. I would have installed the non-Stabiltrak pads but the rotors are shot in the inside possibly from overheating from the stuck inner pads.

 

Does anybody know the difference between ACDelco p/n 171-0974 and p/n 171-0975? I contacted ACDelco support but they referred me to a local dealer who will most likely tell me to buy the correct part. I have also found that no other aftermarket company makes a different brake pad for Stabiltrak applications.

 

Any help would be most appreciated since I most likely can return the pads I bought even though they haven't been used.

 

Regards,

There shouldn't be a difference between the two pads. The ones you bought will be fine. Check to make sure your caliper isn't seized, and clean/lube the slides and cradles.

Always had issues with pads and my '07 Sierra not fitting in the slides correctly, no matter who the manufacturer was. What I found was that once everything is cleaned up, you just have to sand the powder coat on the pad fingers just a bit. Just make certain that you clean and lube your caliper pins and you'll be ok. Raybestos makes a brake lube - comes in a tube. I think it's DBL-2. Any brake lube will work though. A lot of times your front brakes will vibrate, almost like your rotors are warped, when in fact it's your calipers not "floating" the way they should.

Thanks for the advice. Once I get the new rotors I will use the brake pads and see how it goes. Filing the pad fingers seemed to work just fine but it does seem odd you have to do it to begin with. I guess this is one of those 'joys' of owning a new car.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?

      Tire pressure for 37s

      Do you think this width might affect the chalk test with a higher pressure closer to 65psi? I think lowering the pressure makes sense to get the tread to lay flatter
