I am going to put some old brembo caliper from a Ducati on my fatboy.
The brembo came off a dot4 set up and I will be running for 5.
I am going to take the calipers apart to clean. What is the best way to get the dot 4 residue off?
Thanks in advance for your replies
What year is the front end on this?
Like everyone is saying ... the calipers need to be disassembled and the individual parts cleaned with brake cleaner and/or alcohol. The pistons and seals need to come out - you'll never get traces of the old fluid out from between the crevices otherwise.
Good point. I did look Into this and these two part are a good match. Ofcourse we shall seeSomething to consider as well. The master cylinder and the caliper/piston(s) are 'matched' in that if the ratio between surface area of the two are not in some ranges you can get really funny brake feeling. So though you have more pistons in the Brembo your master cylinder may not have the volume to make them feel all that much better.
I have used the info @ https://www.vintagebrake.com/mastercylinder.htm a few times when mixing and matching calipers and MC on older bikes and generally I found the ratios mentioned here did turn out OK though everyone likes a different feel for brakes.
I started to look into this when I tried to upgrade an EX500 front end and ended up with stronger brakes but had no feel to them.

One of forum members that I do work for brought this up...
So are you switching from DOT 4 to DOT 5.0 ? DOT 5.1?
DOT 5.1 is backward compatable but DOT 5.0 should' be mixed or come in contact with anything.
