Redoing front brakes again

[Dustin Jackson]

I value both of the suggestions you guys gave me and so I met you both in the middle and am not doing a full break in procedure. I'm just braking gently for the next tank of gas.

Full disclosure, the only part that I greased was the sliding pins and the caliper piston boots because they were dry, I got a brush in there and removed as much of the old grease as I could from the pin holes and just gave it a light coating of lube and made sure the pins are moving freely.

I noticed when I took the brakes apart that the break dust and dirt had gathered on all the parts that I greased 2 years ago. I live in a pretty dry environment and California doesn't use salt on the roads so I felt that greasing everything would just encourage crap to stick to my brakes so I did this job dry.

Today I took the Tahoe into town and got an amazing carne asada burrito with a good friend and the brakes and burrito performed excellently.

They're legit! BTW, I can't find that email. I'm gonna try some other search terms and will update you.

Hello iamdub, any luck with this brake line information?

Thanks,
Seth

Sadly and aggravatingly, no. I even searched my emails by the entire year. No mention of Kore3 or anything of the nature anywhere. It's like it was deleted. I wouldn't have deleted it.

I swear I took a screenshot of the info when shopping. The trick is finding the laptop I would've dumped that phone's contents on at the time. I'm not giving up yet.

A call or email to Kore3 would make more sense.

Not sure if you saw this or not, or if it's even a clue. But what the hey...

Brake hose type and sizes?

I'm piecing together a braided brake hose kit for all six flex hoses and I'm not completely sure of the sizes. I found a page on Autozone's site that seemed to have all the info I needed, but I don't know if it's accurate. Does anyone know or know where I can find the technical specs of all...

Thanks for looking!

I snooped around their website, and saw their section on ‘Custom Brake Lines.’
6 line set was $189.
Very reasonable money(at least in my head).
However, I got hung up on the required info.
They need lengths. And hose end types. Looking at the pull down menus, they have ‘3/8” (10mm) banjo fitting, 20 degree angle.’

I replaced the master cylinder today on my 2013 Escalade. While ABS bleeding the system, I got a look at the brake hoses on the calipers. 20 degree angle might work on the fronts. However, the rears and almost 90 degrees.
Not sure how that is going to work out…

That reminded me that I tried to find that Kore3 email at least once before. I swear I contacted them not long after I got the Tahoe, so mid-2016 or 2017. I scrolled through all my emails for both those years. According to that second post you linked, it was prior to June of 2017. Maybe I missed it. It's probably from an email of something like "sales@..." or "customerservice@..." and that's why an email search doesn't find it.

That at least narrows it down to about a year range. So, thanks for that!

Agreed. I don't remember what I paid for the five-line set for my S10. I'm really sure it was at least $150.

However, I got hung up on the required info.
They need lengths. And hose end types. Looking at the pull down menus, they have ‘3/8” (10mm) banjo fitting, 20 degree angle.’

I think they have the info in their database for stock hoses and that's what was used to make my quote. I'm lowered, but I really don't have a reason to deviate from the stock hose lengths.

Thanks to @Fless for posting that link, I was reminded that I found this info on Autozone's website. I would definitely confirm its accuracy before having custom hoses made, though. This is why I wanted to find that email from Kore3.

I figured it out. I started scrolling emails in December of 2016 and that's as far back as they go. Apparently, Yahoo deleted my emails older than that. Dammit. I saw some things where you can contact Yahoo to request the deleted emails to be recovered and sent to you. For all the hassle, I'd just start with a fresh contact and quote from Kore3.

While we are still here...

Since doing my brakes and replacing my front brake hoses I thought my brake pedal felt a little spongy so today I bought a big bottle of brake fluid and figured I would go do all 4 corners to get fresh fluid in there.

I used a tube going into the top of a water bottle to slip over the bleeder valve and had my daughter sit inside and press on the brake pedal with the motor off while I opened and closed the bleeder valve.

I thought I did a good job and would have her press on the pedal as hard as she could and then I would crack the bleeder valve for a moment or two and then I would re-secure the bleeder valve as to not let anything travel back up into the brake lines.

We did this on all 4 corners and felt good about it even tho I don't think I flushed all the oil fluid out of the rear lines because it was very hot and taking a long time but some new fluid is better than none.

Took it for a test drive and the brake activation point seems to be much deeper into the pedal travel now than it was yesterday after doing this brake bleeding, did I do something wrong or do I just need to pump up the brakes some more? I just drove it a couple miles down the highway and back.

She should not press as hard as she could. You do want constant pressure while the bleeder is open, but just steady slow pressure for maybe 1/2 the pedal travel and to never ever ever relax back or release pressure while the bleeder is open. If she just stomped on it and you opened the bleeder and then that pedal went to floor before you could close the bleeder, there is air that got in there, IMO.

 

[Dustin Jackson]

@OR VietVet She's only 8 so I just had her press it as hard as she could and hold it and then I would crack it open for a second and then tighten it and then I would tell her she could release it.

You're right, we probably messed up some where but I went through great legths to avoid it. I was hoping that having the tube and bottle over the bleeder valve would help mitigate any error in that area but luckily I have a lot more brake fluid left to try again.

This will be the 3rd time bleeding these brakes just from replacing the front brake hoses

 

[OR VietVet]

Ok, just remember that the air will climb to a high point. It could be higher now and continuing to climb.

YES! LS engines & carne asada burrito. That’s a Chevy commercial right there. Just as the shot is fading out another Tahoe drives up and hands the driver hot sauce.

Today I took the Tahoe into town and got an amazing carne asada burrito with a good friend and the brakes and burrito performed excellently.

 

[Dustin Jackson]

This is the technique I used to bleed my brakes but I had a helper to do the brake pedal part

 

[Dustin Jackson]

Went back out today and had my wife help me this time, we were able to get some more air out of there and its a lot better but still not feeling 100%, might try again next week or just wait until it cools down in fall

Thinking about buying a hand pump vacuum kit from Amazon, it seems dummy proof.. which I need apparently.

That sort of thing is your bag, baby.

 

[Dustin Jackson]

Alright guys I didn’t buy the hand vacuum bleeder, I just went back out today with my water bottle with a hose.

I started by cracking the bleeder and observing what happened, I waited until I got a little stream of brake fluid coming into the hose but not enough that air would be able to get back in. I went into the Tahoe and pumped the brakes a few times and did this until the hose was full of fluid without air bubbles, then I tighten the bleeder and did the same on all 4 corners.

After that I took it for a drive and it wasn’t right still.

I decided to do the same thing but had my daughter help me with the brake pedal, somewhere along the way I realized that when I was telling her to “hold the brake” she wasn’t actually holding the brake and I went and felt the brake pedal and it just went to the floor…

So I caught my kid up to speed on what we are supposed to be doing and told her she needs to hold that brake pedal down until I tell her she can let go.

We pumped a crap ton of air out of the lines, and then I ran out of fresh brake fluid so I went to get a new bottle.

I came back and it was pretty hot out so I told my kid to go in the house, I continued to bleed the brakes myself with my Tahoe running, cracking the bleeder just barely, and using a broom stick to push the brake pedal while I laid on the ground so that I could watch what was happening with the bleeder hose and if there was air still.

Finally my pedal was solid! But I had a stabilitrak light with a “service brake system” message??!!

I cycled the motor a couple times and the message went away and now my brakes feel better than ever.
