Default re bleed?

My n a friend were installing new ss lines and bleeding the lines. We've bled through all 3 sides and on the last side the cylinder went dry. We poured fluid and bled the 4th side until it was good with no air bubbles but was wondering if that was good enough or if we would have to rebleed all four sides again? also would the proper procedure be: right rear, left rear, right front, left front or right rear, left rear, left front, right front?

actually that is not the proper procedure for our cars since the abs module actually sits on the passenger side.

proper bleeding is: LR, RR, LF, RF

what do you mean you let it go dry. you had fluid in it and then sucked air in and let it get all the day to the caliper?

at this point any type of regular bleeding, no matter how much of it you do, wont help. you need to first bleed the master cylinder and then rebleed all the brakes.

Thx for the proper bleeding procedure.

Well... when i was in the car pumping the brakes, I felt the pedal go down to the floor. My friend said he noticed the fluid was down to the lowest line (i will have to double check with him if it was empty or not since I was in the car and could not see the cylinder), but we added more and continue to bleed the last caliper.

Would there be a chance that no air gotten in even if the brake pedal went down to the floor?

Do you have the steps on bleeding the master cyclinder?

Is this the same precedure/sequence for a 92 sc400?

Thanks,

Drivers side rear would technically be closer to the master cylinder than the passenger rear.

By order of distance, it would be PR, DR, PF, DF or RR, LR, RF, LF.

LR is longest from the master cylinder because the abs unit is on the passanger side. think about it....

Bleeding the ABS pumps and lines is a completely different procedure.

fluid passes through the abs unit regardless if it is working or not thus the length of line still comes into effect.

True, but to replace brake fluid through the system, the farthest line need to be bled to the shortest, starting from the master cylinder.
