I was watching this dealer youtube video and he claims the Z-51 brakes are ceramic and only last 15-20K? I know this would depend on how you abuse them but surely they last longer than that? And his description of the eLSD and dry sump was kinda vague too.

I agree that his estimate of getting 10,000-20,000 miles on the Z-51 brakes is way under how many miles most of us will get. There will be more than a few Z-51 owners who get up to 50,000 miles. Of course, as you said, those who aggressively brake, go on the track, etc., will get that kind of mileage. Never before heard of ceramic brake pads on the 2014 Corvette, and I am doubting it -- until we get concrete evidence of that. Any one have definitive knowledge about that please?

I have seen a great schematic on the C7 dry sump oil system, but am unable to locate it now. Will hunt further, and if I find it, will
post it here.

It sounds like the people at the dealer school are providing some miss information or this particular salesman miss interpreted what they were telling him. All corvettes get brembo brakes, the Z51 simply gets bigger brakes with a more sport tuned pad, probably one with a higher ceramic / carbon fiber content to better resist fade. I've been running hawk and Performance Friction Carbon ceramic pads on Porsches for over a decade, they resist fade better, produce almost no dust and actually extend the life of the rotors, not decrease them. If you track the car them yes, pad life will be under 20,000 miles, so what? You won't need to turn the rotors, just pop the top pins on the brembo calipers and drop on new pads. It takes longer to jack up the car and remove the wheels than it does to replace the pads with brembos.

As for the dry sump, it's a simple system. An oil reservoir sits inside the rear of the right front fender and is plumbed to the revised oil pan. Oil is gravity fed to the oil pump and return oil is pumped back into the reservoir. This means the oil pump providing pressurized oil to the motor is never starved regardless how many lateral G's you pull. Here's a good description of the system: http://goaheadtakethewheel.com/rwrt/what-is-a-dry-sump/

Thanks mjw930, the schematic of the type I was looking for. You know a lot about technical and practical stuff, and appreciate your posts!

Here's a little additional from GM, generation 5 , LT1 specific.

Thanks for the great info guys! I just got the jack pucks for my C7. They fit the vette fine. They don't fit my 2.5 ton floor jack at all, lol. But I had read how some people got shorted on differential and trans oil. So I just had to check mine. All was good (no leaks)(sight plugs were torque'd about 1 in lb though) Vin#2107

When did GM quit using universal joints on the rear axles like on my C3? I see they use CV joints now.

anyone else having squeaking in the morning reversing?

Brake pads designed for high temp use will tend to squeal when cold... I once tried to use my carbon metallic mild race pads (Performance Friction 70 compound, I think it was, at the time... great low temp friction, but good up to 1200 deg) for street use on my 1LE Camaro... sounded like I was driving a garbage truck... awful. Stock pads aren't nearly as bad, but I think a dealer will tell you that a certain amount is to be expected. My 2003 would just have a mild amount of it all the time. If you got them hot, it would about disappear. Something that is sacrificed for high temp capability I guess. Buy the way... the pads, as well as the street comp tires, would last approximately four events... about 400 miles. (at Summit Point Raceway).

Pretty sure I read there is a service bulletin out on this for cars with brembo brakes.

Where do you get the jack pucks? I guess that's the recommend way to jack the car?

I'll have a set of barley used Z51 rotors up for grabs soon since my Racing Brake rotors will be here shortly!

 

[thrilled]

I'm easy on brakes.With the 7 speed manual,I downshift all the way down to 1st,much of the time without hitting the brake or touching it very lightly.I had one car over 120,000 miles before replacing the brake pads.

Welcome to our forum ! A bit more information would be helpful bob.vette14. Is yours a Z51 or a base, is it parked outside overnight or in a garage? Is the squeaking from the brakes? If you put the parking brake on overnight and it is damp, it can 'clamp' when you first go to move. But that would be more of a 'pop' sound than a squeak.

All Stingrays regardless of base or Z51 come with Brembo brakes.
