Brake caliper Girling or OEM Audi

I think my wife's Q7 has...6 pistons in the front brake calipers. Your Honda Pilot, which is larger, has one piston per caliper.

I recently got a set of reman'd Girling calipers off RockAuto -- they fit perfectly.

When I did my mk2 VRT I used B4 passage parts, IIRC.

Yes basically the same as Macan calipers, just a LOT less expensive. The feel is great, more pad area and better clamping force compared to the OEM single piston, made my tires scream for mercy. The weight savings is a nice perk as well.

I rebuilt my front and rear for maybe $60 total in parts. Just O-rings and cylinders, they don't really get more simple than this. It's hard to find parts for vented girling calipers since all the guys with solid rotors buy the vented disc calipers as an upgrade.

In the early aughts I scored a set of the Girling 54 calipers from a 16v and my dad and I rebuilt and painted them before installing in my first '84. I didn't upgrade the MC (didn't know better at the time) so the brake pedal travel increased but the braking improved so I kept the set up ... until the next annual MO state vehicle inspection where the car failed for excessive brake pedal travel The 9.4" set up went back on.

There’s two lines, as the caliper is split into two sections vertically. The top two pistons (inside and outside piston, directly across from eachother) are hooked up to one brake line, and the other line hooks up to the bottom chamber and bottom two pistons. If one brake line fails, you still have some brake pressure (the pair of pistons on the non broken line). Unfortunately, this means that only a pair of the 4 pistons will work with just one brake line (all abs cars). This would make your pads wear at a severe angle, and drastically impact your breaking performance. I’d definitely say just find some rebuild kits for your current calipers. It’s pretty easy and cheap.

I've recently upgraded to Girlng 60 calipers and feel a bit uneasy about the pad to rotor size difference. The discs on your car are 280mm. The Audi discs that the Girling 60 caliper came off of are 276mm but slightly thicker.

After getting vehicle to run under its own power once again, which is fantastic. I have no brakes. I've since gone gone in and torn down Front brakes completely, I've found right side metal line leaking. Also breaks & calibers had froze from lack of operation all these years. I'm Replacing all components for front brakes, except I'm rebuilding the girling calipers because they're practically $200 each and it cost 1/4 to rebuild the caliper.

On my '93 I think I've deduced it's the crappy Girling calipers' slide guide pins being worn and allowing for some play in the calipers or it's just a crap design.
