GMC Yukon. Brakes??

[Trix4me]

I’m picking up my 2018 Yukon this morning that is on its 4th master cylinder in 3 months. I’m thinking that something else is the real issue. Anyone else have this problem. Brake pedal goes to the floor at slow speed

Post it on craigslist. "Runs great no issues clean title in hand".

Howdy Trix!

I'd Check Vacuum Lines/Vacuum Pump!

Have They Checked/Changed the Vacuum Pump Yet?

A Friend Of Mine Has The Same Vehicle That's Had Brake Issues Over & Over again!

You Might PM Desperatehills here on MM as well!

You'd Think after 4 Master Cylinders They'd Look at Other Items?
