I just installed new rear calipers on my Z. I did not replace the front calipers. Put new pads on all 4 corners. Wanted to know if, when bleeding, I should bleed the rear corners first (since the new rear calipers are empty), or if, despite the empty rear calipers, I should follow the correct bleed sequence anyways, which is RR, LF, LR, RF for my 02' Z??? Thanks for the help....
Froggy....it comes from the shop manual. There is a specific bleed sequence for C5's (depending on the year) and its not like it is for other cars where you start furthest from the master reservoir and work towards it, like the sequence you specified. My first post is for 2002' Z's (its also good for a few other years, just cant remember which). There is a different sequence for 03's and 04's, I believe
seamus....looked up the bleed sequence for your 04' and its the same as my 02'. RR, LF, LR, RF.
Hey Worm, do you recommend the bleed procedure you posted with the rear calipers being new and empty of brake fluid?? Im a little concerned about doing the LF before doing the LR with the LR caliper empty, even though that is the correct sequence for my Z.
Basically, I dont want to draw an air bubble from the empty LR when doing the LF second in order. Would it be better to do the RR then LR second to get the new calipers filled, then follow the correct sequence??
Worm.....thats what I was thinking was probably the best idea too. Get the gross air out of the rears first, then pump the brake pedal to set the caliper pistons on all 4 corners against the new pads, then bleed several times around in sequence, using your above posted instructions. Should be good to go after that.
Update.....Finished bleeding the system this weekend. Started with purging the air out of the new rear calipers from the RR, then LR and then bled in the proper sequence for my year Z. Worked well and the pedal feel is great. I highly recommend using light, rapid taps on the caliper with a rubber mallet while bleeding to help get any stuck air bubbles out
