Lol, ok

 

the lever effect exists, but it’s irrelevant. There is no net gain or loss of energy by using a larger disc and placing the pad on the outside. If you place a brake pad closer to the interior, you have to clamp harder, but that’s offset by the lack of rotational speed. Considering the clamping force is just a number you can pick out of a hat with an automotive braking system, it means there is no additional stopping power with larger brakes. Thus, it means the only point to having large rotors is heat absorption and dissipation. If you have to convert X joules of energy into heat and to be absorbed and dissipated by a chunk of metal, a big chunk of metal can do that more effectively.

 

In regards to bike hydraulics is just a means of energy transfer. When you pull the brake lever on the bike, you’re not going to suddenly get more clamping force because hydraulics = magic.

 

The only reason disc brakes works on a bike is because bike rims constantly bend a little bit and create a wobble. This means your brake pads need to be further away and need to travel more. With the disc brakes, they are going to stay true, which means you can reduce the amount of travel the pad has, which in turn allows you much greater mechanical advantage. When you pull the brake leaver, you pull it maybe 2 inches. 2 inches of hand travel moving the brake pad 3mm, is a whole lot more mechanical advantage than moving the pad 25mm you need for traditional brakes. You could get the same effect with hydraulics or mechanic advantage, it doesn’t matter. The hydraulic method is just a simpler way to transfer large amounts of energy and creates lighter components.

 

I mean, did you never wonder why every vehicle on the road has the braking power to lock up the brakes no problem, but for some reason sports cars have bigger brakes? Why the hell would they have bigger brakes if a honda civics brakes could easily lock up the tires.

 

heat dissipation is the only reason, not mechanical advantage

Thanks!!

i wonder how brake bias is being affected  when you guys are switching over to the larger calipers??

All things being equal that is incorrect. Bigger rotors put the clamping force farther out from the center line for better stopping torque on the wheel, so physics show that they do stop better. It's

Testing the water to see if anyone is interested in purchasing front brake upgrade for 2014-2018 silverado 1/2 ton trucks or Suv. i have a source to acquire like new loaded calipers and the new rotors

"you could just redesign the oem proportioning valve  internal components"   Yup, that definitely sounds like something people with no knowledge of the design of braking systems, or the trad

I’m not sure. If the clamping force is increased by the caliper, and only on the front or the back, then yes it would be effected.

 

I really want to hear groovey moon, the “engineer” respond

I’m pretty sure these should clear even 17 inch wheels, for those of us the went down to 17 inch wheels since the spare tire on these new Gen trucks is still a 17 inch. It would just have to be a low offset wheel to clear the outboard portion of the caliper. Pics are of both types of spares on 2020 Sierras at a local dealer of mine. Can anyone confirm this to be true? I just need to clear my 17 wheel barrels, my wheels have a concave and zero offset to clear the caliper width..

Any chance they'd let you mount a spare up to see how it fits? That 2nd one actually looks pretty good!

Here is what I ordered from Rock Auto and I got some Stop Tech SS brake lines number 950.66002 from ebay. 

The brake lines aren't really needed, but I figured since I was in there I may as well upgrade those too. The price of the brake pads was stupid, but they also came with a new pad life sensor which I didn't need. I'd bet you will be able to find pads cheaper before too long.

So I started at rock auto and neither they nor anyone else has the drivers side caliper.  It actually appears that a new part number is out for the calipers. I wonder what may have changed.

I don't know. Rock Auto looks to have them both available right now but there is a 2 day delay on the driver's side one.  The stock has been in and out on them for a while.

Could you get a measurement from the face of the rotor to the outermost protrusion of the caliper and the measurement of the wheel mounting surface to the same location on the caliper?  Might help us figure out if these will clear wheels before finding out we need spacers. Thanks.

I'll try to get to it when I have time.

Please let us know on the measurements 

Hey Bud. Just got done doing the swap on my 2006 Z71. Here are the measurements roughly. 

 

Front face of rotor to outer edge of the caliper is 2-1/2" roughly.

 

From face of hub to outer edge of caliper is 1-1/2". If concerned about clearance add 1/16" to your figure.

 

I have 2015 Sierra 20" oem wheels on the truck. Tons of clearance with these.

Let's keep this thread going! Very interested. Just bought a '16 Silverado 1500 with 73,000 miles and it feels like it needs rotors, I've got a shimmy when it under hard braking. It'd be nice to spend a little extra and just upgrade the calipers too.

In theory, your brakes should match your engine. Whatever energy your right foot creates, the brake pedal needs to be able to dissipate.
 

This being said, the 6.2 is considerable more powerful than the 5.3. And I think they use the same brakes. Which means oem should be just fine if you have a 5.3.

Having a 6.2 I cannot say my brakes (in their current state) are confidence inspiring. I have an NBS silverado that I converted to hydroboost and it's pedal feel is fantastic. 

 

I'm going to flush my fluid this weekend and that should help my pedal a bit. I'd like to get more feedback on this topic though throwing money at my current setup.

      OCI, not when but why?

      By Chuck FB · Posted

      I imagine the cold winters up here with repeated short runs in town every day for those that live and work in town and given what I have come to learn on this forum with DI engines having fuel dilution issues, and if they don't change the oil until it says to but keep driving it for a while, I bet all that is just lovely on those finicky lifters.

      AWD conversion to Z71

      By teamjnz · Posted

      I just did some reading and Stabilitrak is more than a what I had originally thought. It is more of a vehicle control system to help the driver in precarious situations. I thought it was only the AWD system. Now I know. So I changed the title for this thread to AWD conversion to Z71

      Sounds like converting will be a bigger endeavor than I was thinking. This truck doesn't have 2Hi like the Suburban did. The Tahoe has 4Hi and 4Lo and a button to turn of traction control.   From what I understand the Stabilitrak uses open diff in the front and rear. When wheel speed is not the same the stabilitrak uses the ABS system to slowdown the spinning wheel(s) to transfer power to the slower non-spinning wheel(s). I thought the transfer case was open too. Being able to transfer power either more to front or rear depending on wheel spin. Maybe I miss understood some information with you saying and power transfer is 50-50. Thanks

      My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.   BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.
