Bleeding brakes

[zodiac572]

Hello everyone, now that ive got the brakes all put togther and adjusted, maybe someone cam answer this, 95 gmc c2500 has abs system , does the truck need to be running to bleed the brakes?

To bleed the lines/calipers/wheel cylinders, no the truck does not have to be running. To bleed the ABS system you need a scanner tool that is capable of bleeding the ABS system. No other way to properly do it.

So the brakes are connected to abs system , to bleed the rear drums do i need a scanner tool for it? Its a 95 gmc c2500

You do not need a scanner tool to bleed the rear brakes.

You DO need a scan tool to bleed the rear-brake section of the ABS unit.

So...yeah...scan tool mandatory. See attachment.

Would you know what scanner is good for it as its obd 1?

Whatever is listed in the service manual...Tech 2, or perhaps Tech 1.

A '95 should be the EBC310. My Snap-On Solus Pro with 8.2 software will not auto-bleed my '97 K2500 with the EBC310. However, the Solus Pro with 14.2 will auto-bleed my '97. So I have every expectation that a Solus Pro with new enough software will auto bleed a '95.

There's a whole thread with a periodically-updated chart listing which scan tools are confirmed to work with various ABS systems. I took a quick look, but couldn't find it.

Just be sure and let us know what worked or didn't for you so that I can keep the spreadsheet updated.
