In 2018 Evoque L538, the rear calliper pistons aren't retracting all the way.

Greetings everyone;

After keeping the button down for 5 seconds, shutting off the engine, and then releasing it after 2 seconds, I was able to retract the calliper piston while attempting to remove the back pads. According to what I've read online, the technique of holding the throttle down won't work for my particular kind of automobile.


The piston wouldn't retract completely even after I used a calliper rewind tool. My new Brembo P 86.029 pads are either 1 mm too thick or my piston is getting caught. I don't know which one it is.

Tomorrow, I will test the opposite side to determine if the issue persists and to rule out a calliper defect.

I would much appreciate any recommendation.

Much obliged.

During my own work on this, I recall feeling confused and frustrated. I had to twist and push in order to fully retract the piston using the tool. I don't quite recall the exact steps, but it seemed like pushing it to its maximum potential, screwing it in half a turn, pushing some more, etc.

To begin, locate the calliper and unscrew the bleed screw. The tension will be relieved. Retighten the bleed screw after the piston is fully retracted.

I am grateful,

It has been determined that the piston may be pushed back around 3 mm at the beginning, then wound back using the tool until it stops. After that, it can be pushed back somewhat farther, just enough to accommodate the new pads.


Easy when you have knowledge about......

The fluid very slightly elevated the master cylinder level; I did not open the bleed nipple.

Before beginning work on the drivers, I retracted the calliper (placed it in service mode), removed the pads, and popped into the house for a few minutes. However, while I was there, the handbrake came on, so I had to remove the motor from my calliper and use an 8/10mm bit. I used an Allen key to fully wind the piston on the passenger side, but it still wouldn't work. To prevent it from winding back in on its own, I put the vehicle into service mode and disconnected the brake calliper. I also tried using brembo pads on my mom's Evoque, but they didn't work either. In the end, I bought ebc pads, and they worked perfectly.
