Brake Bleeding Procedure on 2026 Silverado 2500

[Alex-Rodriguez]

Good morning,

Is there a brake bleeding procedure for brake bleeding on the newer 2025-2026 Silverado 2500 HD  trucks.

 

Recently i did a c8 corvette that gave us bunch of issues by not using a scan tool. To get the MPH limit warning away i had to disconnect the battery , pressure bleed with 30 psi into the reservoir. After the bleeding was done turn the Ignition on and held the brakes insanely hard for 10 seconds and the error went away. Stupid i know i have a autel scan tool now and can do a abs bleed if needed but is it required.

 

Can I do a traditional brake bleed could i simply disconnect both batteries and use my Matco pressure bleeder to flush out the oem fluid and replace with my favorite Castrol SRF.

 

What is the steps to properly to do a brake flush ( swapping out to much higher boiling point fluid Castrol SRF as all our race cars ) nothing is wrong with the brake system on the truck.

 

Much appreciated

Alex

If I were a betting man I'd say you need a bi-directional scan tool in order to get trapped air out of the ABS. That's the trend things have been heading toward for many years now. They don't want anyone working on "THEIR" vehicles at home.

 

The, "you bought it, but WE own it" mentality is rampant today.

 

I always just kept the master full, and used a vacuum bleeder to pull the new fluid out. I would start off by emptying the master with a turkey baster, fill with fresh fluid, then start at the right rear, then left rear, then right front, ending at left front.

subscribe to alldata.com, that will have gm's brake bleeding procedure.  and what you have to do likely varies, as if you just replaced a caliper and the MC didn't go dry, you most likely can just do a normal bleed on that corner, but if you disconnected lines at the MC or the abs unit, or let the MC run dry while doing work, you'll have to do a more extensive/complicated bleeding procedure.
