Tonyrodz's Tahoe Build Thread

[Tonyrodz]

Oh shit, hope the trans didn’t get damaged. So you stopped right away, that should have saved it. Double clamp it, and check on it by pulling on the hose to try and separate it or add a flair like others have said.

Done and done. Trans fluid has really gone up in price.

First thing that came to mind.

Damn, I was trying to go back to sleep since it’s 1:30 am here and now I got that song stuck in my head. So I’ll bet you might end up with it in your head too @Tonyrodz. Guess we’ll both be singing the same song at one point this morning. Hope you have a great day Tony!

Oh man, just seeing this. Almost 9 pm here. Had a long 12 hr day at work today--again. Hope your day was better then mine was Mark.

A new issue popped up with my 03. When stepping on the brake pedal to stop, the pedal slowly goes to the floor. Letting up and then stepping on it again the pedal feels normal, then again slowly goes to the floor. There's vacuum going to the black canister that's bolted to the booster. Also my abs AND brake lights are lit on the dash--but it's been like that for months. Brake fluid level is good. The pedal issue is new. Any ideas or clues?

Master cylinder took a poop...

I thought it might've been the booster, but was told no. Thanks for the quick reply @George B .

Leave the lines attached and unbolt the master cylinder from the booster and pull away and see if you see WET. If you do, that fluid is leaking out the back, BUT, the master cylinder CAN take a poop by bypassing internally and never leak out the back. I do agree with @George B

I was just doing this test,check it out.https://www.tirereview.com/test-vacuum-power-assist-hydroboost-braking-systems/

 

[Tonyrodz]

Does anyone know where the check valve might be?

Very handy--thanks for posting the link @tungsten .

@Tonyrodz
You could have a really slow leak too. I would take a really good look under the truck. Can't remember, do you have known good or SS lines on that truck?

I have SS lines on it. Been installed for around 5 years now.

if your not seeing any puddles from a line, master took a dump. theres o rings on the shaft, they wear out and fluid bleeds past the o rings. some times you'll see its wet under the master where it gets bolted on, also a sign the master is bad.

I looked earlier and saw nothing leaking, with good brake fluid level.

the master is an easy change. You can bench bleed it and install it in an hour. no need to bleed back to the wheels if you are careful.

Yes, careful bench bleed and then leave the bleed hoses attached at the threads and curled over in to the fluid and leave the ends submerged while you carefully attach at the booster and bolt up. Then remove the caps the lines that are curled over are attached to and immediately thread the metal line on and tighten. Then can pump up very slowly and bleed at lines where they attach at the master cylinder. Hopefully, during all of this, the metal lines have been kept in place pointing up a little so the fluid in the line did not just sit there and drip till it stopped. You want to keep as much fluid in that metal line, while apart, as possible.

Ahh bűgger!!
Mine was doing that and just ended up getting R A to send a replacement master over here to me. Was an easy fix and I was able to crack all my bleed valves without issue! Phew!!
Reminds me,need to top up the fluids !!
Hope is a easy fix Tony

 

[89Suburban]

You can do it Tony!!

 

[OR VietVet]

Piece 'a cake, @Tonyrodz.
