04 Gmc 1500 Brake Flush.

I saw a brake flush done on Trucks (Second chance Silverado Part 4) and wondered if a Tech II was required to do it?? If not, I am going to get one of these.

No, the Motive bleeders do a fine job, making it much easier. I have one, and recommend it.

Thank you. What pressure do you pump it up too??

I think Motive says no more than 20 (maybe 25??) psi. I have the universal adapter that I use on the truck, so I keep the pressure lower - no more than 20 psi. I only need to pump it up 2-3 times to do all four wheels, keeping pressure above 10 psi the whole time.

 

Depending on what vehicles you have, order carefully. The adapters to the vehicles cost like $20 each. I have one to fit my BMWs, and the Motive universal clamp arrangement, that fits everything else, including the Chevy and the Subaru.

NO Because the fluid in the ABS module at the actuators will no be flushed unless the module is toggled. You do not have to use a Tech 2 just a similar scanner that has ABS functions.

When you apply the brakes in a normal stop the fluid does not go through the actuators and bleeding without the ABS toggled will still leave the dirty fluid in the module.

Thanks. Did filling it once do the job?

Thanks. We just did the rear brakes on our truck. Put on new rotors too. We could not get the bleeders open to push the pistons back in th calipers, so did it without opening them. Did we push dirty fluid back into the ABS module? Or no?

 

Would propane torch have enough heat to open the bleeders??

Anytime you do a brake job correctly you must bleed first to get the dirty fluid out or risk damageing the ABS module.
