    Losing Brake Pedal Pressure

    It is a new Duralast master cylinder. It looks like the one I originally bought had a defect. The replacement works perfectly.

    Losing Brake Pedal Pressure

    Alright, I had a good chance to look at my Yukon today after work. After spending a couple of hours trying to find the leak and it turns out it was internal. A shout out to @swathdiver for suggesting the master cylinder. It turns out the one I bought from Autozone was leaking internally and...

    Losing Brake Pedal Pressure

    Howdy, My '05 Yukon XL has an issue where the brake pedal loses pressure when at a stop. To the point where it starts rolling through the brakes and the "Service Brakes" alarm sounds. I recently changed all the steel brake lines, master cylinder and bled the lines a couple times. That thread...

    Mushy Brake Pedal After New Brake Lines

    Thanks for the info! I will try this when I get finished installing my new mc. Turns out the old one was built on Feb 22, 2005. Defiantly time for a replacement!

    Mushy Brake Pedal After New Brake Lines

    @argus Its a little tricky to find the setting that bleeds pump in the Foxwell Scan tool. Here is a video that uses a different scan tool, but it’s very similar. Look around a bit in the abs section and you will find it.

    Mushy Brake Pedal After New Brake Lines

    I’m using a Foxwell Scan tool. Here is the Amazon link: https://www.amazon.com/dp/B072VGJ7S8/ref=cm_sw_r_cp_tai_IvtBCbMW2R6RQ As for the slightly squishyness you are speaking of. GM SUVs and pickups have always had a slightly squishy brake pedal. As long as you are not sending the pedal to the...

    Mushy Brake Pedal After New Brake Lines

    Thanks for the reply. To my knowledge the MC is original. I've never replaced it. Unless the previous owner replaced the MC, than its the original one from the factory. It may be time to replace it. My Mom was driving when the brake lines gave out on a highway with traffic lights on it. She said...

    Mushy Brake Pedal After New Brake Lines

    Sorry for the late reply, but thanks for the advice. I had my younger brother pumping the pedal as I was going around and opening the bleeders. Hopefully, he did not go to the floor with it.

    Mushy Brake Pedal After New Brake Lines

    I already used an OBD tool to get the ABS to bleed the air out of it when I bleed the system. I have a feeling that there is still air in the master cylinder. I will bleed the master cylinder again when I have some time this week or next weekend, following iamdub's suggestion about pushing the...

    Mushy Brake Pedal After New Brake Lines

    I did bleed it already. I will try again. As iamdub mentioned to go all the way to the floor when bleeding. I did not do that. I will when I bleed them again.

    Mushy Brake Pedal After New Brake Lines

    Howdy, My '05 Yukon XL recently suffered from the dreaded rusty brake lines. I replaced all the steel lines with new ones and filled and bleed the system, including the ABS pump. However, my brake pedal is still mushy and goes to the floor easily. I have heard the master cylinder can wear out...

    Brake Pad Issues '05 Yukon XL

    Howdy All, My Yukon XL has been having an uneven braking issue with the brakes. The front pads are wearing unevenly on driver side. To clarify, the pads wear evenly but the braking surface does not. The driver side rotor has a smaller braking surface than the passenger side, and yes, it does...

    Water Leak '05 Yukon XL

    Thanks for the reply. I have never had the water pump off before, but I can't imagine it will be as a big of a pain as the 6.6L Zuzu (Duramax) water pumps. But is it common for the gaskets to fail on these water pumps?

    Water Leak '05 Yukon XL

    Howdy All, I have a '05 Yukon XL with the 5.3L and it has a coolant leak. It took me forever to find it, but eventually I did, and its leaking from behind the water pump. I was wondering if anyone knows of any common failure points on the water pumps for the 5.3L engines? I am unsure as to...
