Dust Boots
Has anyone had to change them out? The shop told me I need new calipers because of the dust boots.

Seems like massive overkill. I assume no individual caliper parts show up in real OEM. I’d measure the pistons and contact a Brembo parts supplier to see if they can help identify the boots you need. I rebuilt 6 piston StopTech a few years ago with new pistons and boots and found all the part numbers, but it is a much smaller company with many fewer applications.

I found the boots I need, but I’m having a hard time finding a place that will do it.

How are the boots in need of replacement already? I always thought they were essentially lifetime parts. Certainly not on a 2 year old car. Were they damaged? Defective? If they are defective you should be able to get that fixed under warranty.

DIY. Lots of video and text DIY if you google. Or take the caliper to a machine shop and ask them if they will do it for you. If you need a shop to do everything, keep calling around — there has to be one that will take your money for a small job that requires cleanliness and care more than serious mechanical expertise.

Cracked and dry rotted. Said it's from extreme heat. I track the car so I know it gets hot.

I wonder whether titanium shims would help? I think they are primarily used to reduced fluid temperature but maybe they would also prolong boot life. Nothing is harder on a car than tracking it. The track guys drive harder in one 20 minute session than the guys here who write about how hard they drive their cars on the street do in a week.

The dust boots are very easy to replace. All you need to know is the piston sizes. Keep in mind not all 3 pistons are the same size. You can source caliper rebuild kits from all sorts of vendors.

DIY my friend. If it's just the dust boots, It's simple and easy. HOWEVER, if you don't spend a lot of time with the car in the rain...fagetaboutit. Racing Brake made special silicone dust boots for the GT-R. And they STILL burn on the track. STILL. Wait until they're charred little pieces of dust, and THEN replace. Shawn |

I barely drive the car outside the track lately. I’ll take care of it during the winter. Tires and rotors has turned into my biggest issue now.

Miata's, sure. Cheap but slow. Find a great performance car in 2023 with less than a 235 mm width tire. Good luck. Anyway. Sorry I missed this for a while. Been busy. If you really want to replace the seals, those kits above are OEM, and great. Shawn |

I actually looked at the Racing Brakes Dust boots, you had no luck with them?

Full rebuild kits would include 12 per caliper. Not just the boots but the actual piston seals as well. Done that too. Don’t know if this kit includes them. Shawn |
