Inspect your brake calipers if you have a g80 rear axle

[LordWayback]

If you have a 1999-2006 gmc Chevrolet suv/truck with the g80 4wd rear axle with dual pistons mine failed and will not hold brake pressure at the pedal while running

Yep it just sucks because it can’t wait I’ve been waiting at the shop for 2 hours I may be here for up to 6 more hours due to it being a Sunday on Friday i couldn’t get any brake pressure despite bleeding straight to floor no resistance, woke up waiting for tow truck tow truck arrived and I magically had brake pressure because it’s colder the bad seals sealed enough to allow my truck to be flat bed towed

I figured because it happened to me it’ll happen to someone else if they don’t get them checked out

just happens from age, part of owning a older vehicle, the gmt800 stuff seems to hold up slightly better than the gmt900 I have already been thru 2 sets of front calipers, finally bought some heavy duty new oem towing rated calipers

Atleast it wasn’t a steer one

Mines been pretty reliable minus front end suspension and steering and the radiator really oh and fuel pump relays

I thought that was just a dust boot portion

 

[Doubeleive]

it is but if that's blown out then dirt and contamination got in there

yeah That makes sense.

Rubber never ages well........

( Check the one in your wallet )

 

[LordWayback]

yeah That makes sense.

Doesn’t help that I mud bog

 

[LordWayback]

Why you spend all that money and put yourself through hell? Get you a small jack and a toolbox to keep in that rig at all times so when shit like this happens you can save yourself hundreds or more!
A new caliper from advance might be over 100$ and it can be swapped out in 30 min
I think it’s a 19mm 2 bolts on the bracket and the bleeder might be a 8mm
You would just need a helper to re bleed the breaks
I’ve done multiple brake calipers and wheel bearings on the side of the road and in auto zone parking lots where I did not have the money to afford a tow truck+shop visit I knew I could figure it out and get it fixed so I could get back home.
If moneys tight start off simple like I did with a harbor freight socket set and a crescent wrench and go from there!
And if you don’t know YouTube it!

i never experienced the brake pedal randomly loosing pressure and they are currently saying it’s not the caliper and are running around like chickens with their heads cut off i did my front brakes just fine before but these rear brakes wouldn’t bleed at home like normal the second the brakes wouldn’t bleed normally I instantly put it out of my league due to insurance purposes

I also have AAA unlimited distance tow however them refusing a caliper job because the “caliper is fine” while when you compress one piston the other doesn’t go up which is a big no no

They said that my master cylinder has failed and it’s gonna be a lot more than a 5 bolt job and Flush

 

[LordWayback]

bad seals, it happens

Quick update this is a $900 ordeal master cylinder is clogged, brake caliper inoperable

 

[LordWayback]

Oh and I need rotors they’re below minimum and one is gouged

Mud bogging eats the dust boot rubber up because you get out of the bog and then drive and build heat with the mud packed in there. The actual seal, that holds the fluid back, is exposed to anything that follows after the dust boot opens up. I mud bogged in Mo., man that was way more fun than off roading here in Oregon, and at the events, we had pressure hoses to get in there to blow the mud and crud out before hitting the asphalt.
