Owner reviews for brake caliper

I had a friend with those 11” rears on his mk3. Nice upgrade when paired with his 312 Brembo boxsters.

Must do, the WJ knuckle swap with Akebono calipers. Teves calipers are junk, and the factory XJ calipers are freakin worse!

I've been running the brembos with ss lines, wildwood MC, stoptech rotors, hawk pads and dot 4 for years. And I run hard. 0 issues.

I have installed those and drove them super hard at the track and they did great.

I rebuilt a caliper for $13 and it went well, but I was able to get all the parts.

I’ve rebuilt the front calipers, upgraded the rears to MK4 callipers, new pads and rotors, new proportioning valve, TT stainless brake lines.

AG pads so I assumed AG calipers. Told to order Girling.

It takes a larger master cylinder to push more fluid to four pistons. The surface area of all 4 pistons pushing on the disc is slightly larger than OE. A larger (thicker) rotor is being used and I'm not sure how to calculate that into the equation or if that's even important. Regardless if you have the oe mater cylinder using Porsche 4 pot calipers you will have to get a larger master cylinder.

Raybestos calipers. Actual garbage in a box. Blown out seals stripped out banjo bolts. Even a cracked caliper.

Two calipers failed in the first year. I tried to repair it when I finally took apart the seals were junk and they had never been put in properly at manufacturer. The pistons had rust on them! Understanding manufacturing can go bad. Now today I heard a grinding and pulled my wheels off my Jeep only to find a third caliper had frozen and completely ripped through the brake pad and damaged the rotor. Not to mention all the paint that was so pretty on these things has peeled off.
