4 Piston Big Brake Upgrade from 2019-20

[blueinkd]

Oh man. A gloss black would look nice too!! I want to hear the results from the guy already on the 07+ brake mod going to these. I have that whole kit sitting in boxes on garage floor and my 4 piston calipers should be in soon. My preference is to install the 4 piston set up. Coincidently the 08 tahoes use the same rotor as a 2019 Trail boss. According to the parts house catalog. I also have an LT with hydroboost and I haven't seen this being discussed either.

whats a speed bleeder?

I use this thing. Works on everything.

It lets you bleed your brakes without a second person opening and closing the bleed valve. Basically on the pedal release there is a valve inside the bleeder that blocks air from entering the system.

Calipers are in!! Got them keeping my controls arms company!! Away from the 08 Calipers!!

My calipers are scheduled to arrive on Saturday via FedEx

In regards to the texture on the calipers, I'm going to hit them with a 36grit flapper wheel on my die grinder. It will make fast work of it.

I'll post up some pictures when I get to it.

Man I was thinking the same thing. I got two grinders that could polish them up. I'm ask the wife for tips, see what she says

I knew you were going to do that.....
You have to let me know how long it takes.
I thought about that too. They are so rough and will look awesome all smooth and coated.....
I'm so lazy when it comes to that.

Are you going to pull the pistons and seals out and have them powdercoated?

That's the plan right now.

All efforts right now are on finishing up these LSA blowers, selling them and getting my 6.0 into the engine builder

We're going to get off track here, but

What LSA blowers?

Are you going to put a 6.0/LSA blower on your PPV?

A while back I had a Callaway Silverado, 6.2 with a small maggie
That thing ran great and got pretty good gas mileage for a 6.2.
Only a 2x4 though so I sold it.

It had callaway branded stoptech 6p calipers front and back. Stopped really, really good.

This is getting a little out of hand there....smoothing the texture of the caliper....but I agree.
I'm going to install and test mine first.
Then see if they fit on the back.
I also think the caliper would look better with that front ridge shaved off. Its steel so I don't think that would compromise the caliper too much.

Then you could put some heat resistant stickers on it.....I haven't seen any Tahoe ones.

Yeah many have shaved that forward facing ridge off with no issues

OK, I get the feel you know more than you're letting on.
You're making me feel like frodo, and you're gandolf....lol

Do you know if these calipers will fit on the rear of my 2003 Tahoe?

 

[91RS]

What would be the best way to shave off that ridge? It almost sounded like some people have had a machine shop do it and now I'm seeing people talk about grinders, flap wheels, etc. I got the Brembos installed on my truck yesterday and the pedal feels great and they stop great. I was planning on swapping over my old calipers with the EBC pads to my Yukon but now I may want to use these 4 pistons if I can make them work with the wheels I have because I don't really like the EBC pads.

I have been playing with this particular mod/upgrade for over a year.

IN regarded to the fitment on the rear, I have not tried. But with all good mods/upgrades, someone has to be the test monkey and try it.

The main issue I would see, is trying to find the correct sized 13.5 "rear" rotor.

You've probably already covered this. But you'll need a proportioning valve, too. The rears typically do about 20% of the braking due to weight transfer. Without changing the brake bias, you'll be activating your ABS a lot more often.

I seem to remember people swapping to the GMT-800 two piston rear calipers as an upgrade for the 900s.

I saw a YT video about this the other day, I will see if I can find it

So I see guys on youtube doing this 4 piston upgrade from a 2019 silverado to their 00-06 silverado.
Has anyone here tried this on the Tahoe?
Should fit right?
Seems pretty easy and straight foreward.
Like $350 in parts.

I would like bigger brakes.

I would like to know if anyone has put these on a 2017 Tahoe, what parts were needed, was it a bolt on or is machining required. Thanks in advance

The 2021 Tahoe shares the same front caliper as the silverado.
If the 2017 front wheel spindle is the same as the 2021 Tahoe it should bolt right up.
I would say you have a high probability.

I'd like to shave that ridge off to.
I think the folks here were referring to smoothing the rough texture of the caliper with flappers and grinders.
When you say brembos do you mean Brembos? Or the 2020 Silverado caliper?

I thought about buying a metal blade for my chop saw and just shaving it off but its a lot of steel material, will make a mess and could bind and launch a 20lb football into my groin.....So I put that on the back burner.

You should post a PIC or 2 of the brembos on your truck.
