Introduction
Operation carried out on a Mégane 3 1.9 dCi 130ch.
-
-
-
Place chocks behind the wheels that are still on the ground, shift into gear and release the handbrake.
-
-
-
Insert a screwdriver behind the cover and tap with a hammer to unlock and remove it.
-
Using a 30mm socket remove the nut.
-
-
-
Loosen using a 13mm socket.
-
Lock with a 15mm flat wrench.
-
Remove the hose from its housing to have more play.
-
-
-
The caliper bracket is secured by 2 screws that you will remove with a Torx T60 male bit.
-
The brake disc comes out by pulling on it.
-
-
-
Brake fluid may overflow when you push the piston back.
-
Check the brake fluid level.
-
Push the piston back with a suitable tool as the piston is screwed in, so a clamp is unnecessary here.
-
-
-
Clean the bearing shaft, threads and seat.
-
Clean the caliper support and especially the accessory area.
-
-
-
Before installing the new disc, apply brake cleaner to both sides to remove the paraffin which serves to protect the metal from rust.
-
Reassembly is carried out in reverse order.
-
Once reassembly is complete, press the brake pedal several times to put the piston back in place.
Check the brake fluid level in the reservoir.
To break in new pads, do not brake hard during the first 200 km.
The effectiveness of the first braking actions may be reduced.

Good morning,
What are the tightening torques for the hub nut in particular?
THANKS
Attention: it is worth remembering that this tutorial is valid for replacing discs WITH bearings. If the new discs do not include the bearing, it is necessary to recover the old bearing and it is much more complicated… (the Oscaro catalog includes discs with bearings and discs without bearings)
WARNING: SAFETY: Hello, very clear and precise tutorial. Very good, but using concrete blocks as jack stands carries a huge risk, as in the photo in step 1. It is absolutely not made and designed to support the weight of a car. To be avoided!!!!! A friend of a work colleague was crushed by his car using concrete blocks as jack stands and unfortunately, he died!!!!!!! This kind of photo should not appear!!!! There are alternative ways to jack stands to wedge a car that are even safer than the jack stands themselves!!!! But never concrete blocks!!!!
Be careful on Megane 3 I needed a 36 socket! Not 30 as indicated. Otherwise perfect
Thank you for this clarification. I would have made a mistake. Super nice!!!!
