Nice work Pal. Ideally you want to cover brake pads pins so they don't get painted. As paint can stop brake pads moving freely. Also good is to apply cermiac grease on threads so bleeding nipples don't size up after few months.

Thank you! Pins didn’t get painted and I cleaned up with a scotch pad. I’ll remember the ceramic grease for the future!

Nice work, great video!

[@maxcrowner4431]

Wicked video! I’m looking at doing similar but I don’t have a compressor or spray gun so will be using rattle cans. Did you use any high heat resistant paints or primers? Or an etch primer? As the callipers are aluminium right?

[@LukeAston]

No this was just 2K paint and any other paints should hold up no issues. You can etch prime if you wanted to but a normal primer will work just fine with the callipers being aluminium

Nice video, thank you. Can you please tell me which rotor you used, was it the Mercedes, ML 55, or ML 500 rotor, and if so, did you have to bore out the center bore and/or the lug, nuts, or trim down the brake pad post inside the caliper so they won’t rub on the rotor? I have these 18 Z calipers and I’m using them with a S4B6 rotor, no modification needed, but the offset of the rotor isn’t ideal as it pushes closer towards the outside of the caliper. Any information would be appreciated. Thank you.

[@LukeAston]

I used the ML55 rotors and used a die grinder to shave a bit off the centre bore. Nothing else is required other than taking a tiny bit off the centre bores and it all bolts together like factory

[@williamhansen1580]

@@LukeAston thank you kindly. Did you also change the rear brake set up as well, and if so, what did you go with? Thank you kindly.

[@camjones1106]

Any chance you could measure the overall width of the 17z

[@p0intdk]

If you are going to replace the pistons anyway why not keep them in thru the whole proces?

[@LukeAston]

I didn’t rebuild them last time so I wanted to get any paint or build up out of the piston walls before I fitted new ones
