Hello all,

I just picked up a 2006 A4 2.0T that had been sitting for about a year. The seller told me that the last time it was in the shop, they had recommended a caliper change to the driver rear. On my initial drive home I noticed drag on and heat from the driver rear. Today I dismantled both rear brakes and replaced pads/rotors and compressed both calipers back and put things back together. When I wired in the ebrake cable on the driver side and moved over to the passenger side to reassemble everything. Once the passenger side was done, I went to mount the tires and noticed the driver side wouldn't move...not an inch. The ebrake cable lever was completely seized! At this point, at least to me, it was evident that the driver rear caliper mechanism was toast. I purchased 2 rear calipers, re & re everything, performed a 2 man bleed (on just the rear calipers) starting with the driver rear, over to the passenger rear, and then back to the driver, and once more the passenger. I mounted the rims and went for a road test.*

Initals brake pedel feel was very soft and to the floor...but the car did stop. I proceeded to perform multiple 80-30kph soft braking to beed in the pads. I stopped the vehicle on a flat surface and left in neutral. Got out, took a look and the factory film on the rotors had been removed and there was slight smoke from the rear brakes. Continued on for a good 20 min drive to cool the brskes. The pedal did feel a little better as the drive continued so I am hoping that the soft cause is because of the new pads/rotors. I also tested the ebrake cable and although it did hold the car on in incline, the lever has to be pulled pretty high (almost topping out). Another thing that concerned me was when I got home, the driver rear rotor was significantly hotter than the passenger rotor??? And there was slightly more copper color on the driver rear rotor than there was on the passenger.

Could the ebrake cable be "dragging" on the driver rear more than the passenger?*

Could the 2 man method to bleed be not sufficient enough to release all the air in the system?*

​​Any insight or thoughts would be appreciated.*
