When to flush brakes?
When to flush brakes?
I'm going to install legend calipers, SS brakelines, and new pads and rotors today, time allowing. I just would like to know if I should change the fluid first before installing the new parts or wait till its all installed then flush the fluid. My thinking in doing it first is to avoid getting old crap fluid in my new lines and calipers. I'm not worried about wasting any fluid or anything like that, more concerned w keeping it clean and fresh.
you are correct.flush the system till its all clean fluid thru the old parts
prevent possible crud issues
you will need to fully bleed the system after new parts on too
use DOT4 spec fluid,,need average 1.5 qts for full flush
before install, prefill new calipers as able with oil squirt can and fresh dot4
I would replace calipers and lines first, on the old brakes, so you can do the MANDATORY 2 ABS TEST after lines have been open,
without damaging the new pads and rotors
then do the new pad and rotor install
a couple of brake line plugs` $1 at parts store, slip into lower end of brake line to prevent total loss of fluid from master cyl--that really makes bleeding a pita if master empties itself
Let new fluid run thru new brake lines into container, then install lines on new caliper (already mounted)
note: 1 new crush washer goes on each side of the banjo fitting/brake line connector to caliper
note2: its way better to loosen the line at its separation point before removing its clip to strut ..ck it out and you will understand
reminder to all special TL bleed order Driver front = LF then RF then RR and LR
its possible to get air trapped in abs controller and only way to get it out or even know about it is do 2 abs active full stops from 45mph,,find gravel or water and swerve wheel wildly to break traction
if 2nd time had better firmer pedal there was hidden air in abs
now its made its way to caliper system,,rebleed all and then its done

Thanks a lot! I got 4 new banjo bolts and 8 new crush washers. I got the fluid from a Honda dealer, I'll go check the DOT rating of it but of I am remembering correctly they gave me DOT 3.0. I get a break here in 30 mins. I'll go check then. If its 3.0 is that bad? Should I hold off and get 4?
Back when these cars were brand spanking new, DOT 3 was the standard at that time. Apparently it's still ok, or I don't think that the Honda dealership would be still stocking it.
It's like everything else, there's always something newer and supposedly better. Some fluids are going the synthetic way with silicone and reformulations for longer durability. I'm sure that there are some benefits to using the latest updated version, especially when completely rebuilding your brake system.
