What are 18Z calipers?
The 18Z caliper is intended to accomodate a 350mm rotor, which is larger than the stock rotors that came on any of those cars. 18Z’s also work extremely well on the B6/B7 platform OE 345mm rotors. This will produce a braking coefficient that is dramatically greater than stock OE brakes.
What cars have 17Z calipers?
The Brembo 17Z caliper is an excellent upgrade to a number of Audi and VW platforms, especially the B5 S4 and A4Q, the B6 or B7 A4Q, or the VW Mk5 or Mk6 Golf or Jetta in all their variations, as these calipers are built to accomodate a 330mm rotor, which is noticeably larger than the stock rotors that came on any of …
Are calipers different sizes?
Brake calipers come in a lot of different sizes and styles but they all do the same thing. They push friction material – that’s the brake pads, to you and me – into the spinning brake disc, slowing the rotational speed of both the disc and the wheel it’s attached to.
How can you tell a fake Brembo?
Anti-counterfeiting card for Brembo High Performance parts All you have to do is scratch the silver strip on the back of the card to reveal a 6-digit code to enter on the website to check that the component is a genuine original.
Are all brake caliper pistons the same size?
You will notice that the Rockets front Brake Calipers have two different size pistons in them. The leading (lower) piston is smaller diameter than the trailing (top) one.
How do I identify my Brembo calipers?
Check for the Brembo hologram, which can’t be faked, on the product label and, for further confirmation of authenticity, snap a photo of the unique QR Code on the sealed product box. All brake discs are marked with the Brembo code and logo and with the ECE R 90 approval (available for product codes from November 2016).
Are all Brembo calipers the same?

What is Shimano V brake?
V Brakes are the most common term for this style of brake. Shimano actually named these and other brake companies label them “linear-pull” or “direct-pull” brakes. These brakes are extremely powerful. They are most common on mountain and off-road bikes. Disc brakes require a compatible hub, wheel rim, and frame/fork.
Why do brake calipers have different size pistons?
By having pistons of differing size in thencaliper, the brake designers are able to tune the distribution of pressure across the brake pad. This can allow them to improve the brake noise, compensate for brake pad wear,make changes in the brake output, or make other performance changes in the brake behavior.
Does caliper piston size matter?
Elongating the caliper to accommodate 6 or more full-sized pistons means more flex in the caliper due to extended length. Caliper flex decreases clamping force and is the enemy of any brake system. Adding more pistons of any size means boring more holes into the caliper body, which creates more flex.
Why 17Z brake calipers?
When combined with the 330mm rotor, the 17Z calipers will account for substantially more braking power, and look fantastic on your car all the while…and at a price substantially lower price than retail shops.
What kind of caliper does an Audi 18Z have?
The 18z caliper is a big, modern, and proven caliper designed and manufactured by the braking system Gods themselves, Brembo. It’s an excellent upgrade from most stock brake setups (and the fact they look really cool also helps). Audi Q7 caliper forward of the wheel hub.
What is the difference between Brembo A4 and 18Z calipers?
The carriers for the standard A4 calipers are threaded themselves and the standard bolts screw into this tread, the 18z calipers do things a bit differently. The Brembos have smooth, unthreaded mounting holes, like the hub itself.
How many pistons does a disc brake caliper have?
Each caliper has 6 pistons (“6-pot calipers”), 2 of which are much smaller. This smaller pair of pistons is designed to aid even pad wear and should be the first pair to meet the disc as it turns into the caliper. When mounted forward of the hub this smaller pair are at the top, rearward of the hub they should be at the bottom.
