Couldn't use the blog setting control for some reason so hope the following will be displayed properly......








Was not in the menu but I just didn't like the feeling of the brake performance and the pedal feedback.
Also, the disc and the pad were not making good contact.

So, started the brake overhaul.

Based on the feedback from another owner, decided not to send the caliper out for the rust treatment and the premier coating due to virus situation causing big delay in their service.








However, after looking at this, I regretted the decision…..












Can't remember the last time I had to use the plier to remove the rubber boot…..
In fact, part of the boot torn off and stayed inside the caliper groove as the rust was so severe that it managed to chew into the rubber material and held it tightly.

Addition to this heavy rust, some sort of wrong grease was used in the past that I couldn't move the pistons even for 1mm.
Couldn't believe how hard it was to remove all these pistons out of the caliper bore.

I knew these calipers were serviced in the past because the slider pins were at the wrong positioning at the rear side and looking at the rust on the pistons, they were replaced in the past but not done properly and none of them can be re-used.








Some of the slider pins had to be replaced as the rust already went too far.



Although I started the refurbishment, I didn't like how the new boot would sit inside the groove of caliper body so at the end,
I had to take my trusted rotary router out as there were hidden rust still left at the upper side of the groove.
