Hi, great when you have all 4 new !
I started with the new rear calipers, new pads, new flexible hoses.
I took out the old brakefluid from the brakereservoir and added new fluid. I used dot4.
I understood that the rear Flex hoses were a hard job. It was not too bad actually. When changing the flex hose, the brake fluid kept coming (old fluid getting out the lines, so that was good
) and after the new flex hose was in and attached to the rear hard line, first I let the gravity let the brakefluid get through it. I capped the hardline with the cap from the brakecaliper from the bleedingscrew.
Then bolted on the brakecaliper . I did not prefill them.
A fun task was to set the clearance on the rearbrake pads. It is an interesting design, and not too difficult if you have new calipers that work like they should.
I did the bleeding of the rearcaliper, then set the clearance, bleed again, re-measure/re-adjust the clearance again if needed.
