Brembo caliper—gold on cast iron really shows the dirt and gets tough.
But I think it’s come out plenty clean (by our standards).
Let’s do a caliper overhaul.
We’ll start with the rear.
The dust seal area had some buildup, but considering the mileage and age, I’d say it’s in good condition.
We finished it with wet blasting for a smooth, slick surface.
It’s like rejuvenation from the inside out. Feeling like Italian pants today (*’ω’*).
Don’t trust something just because it’s a manufacturer’s product.
Mistakes can happen wherever people are involved. I believe that small, steady efforts bring good results.
CCI MR20 Metal Rubber A gem I’d really like grease fans to try.
Ultra smooth operation.
Now we’ll overhaul the 30/34 Brembo caliper.
Overall there’s dirt, probably from the casting and color. Since it’s an anodized caliper, the work is relatively straightforward.
And so it’s come out clean too, then we completely dry it in the oven before assembly.
We reuse the pistons and replace the seals and O-rings with new ones.
Why doesn’t Brembo have this O-ring spec?
Make sure you get ones rated for fluid resistance.
Once you’ve finished bleeding the fluid, take it apart again and work the piston back and forth—it’s really effective.
The seal seats quickly, so the feel becomes premium right away (*’ω’*).
And that’s the front assembly done.
The rear assembly and oil and clutch fluid exchange are for tomorrow.
