Renault Sandero (2nd generation): Front Brake Rotor Replacement

On the Sandero II, front rotors are replaced as a pair, on both sides of the same axle, together with the pads. Rotor life depends on driving style. Replace the rotor if you feel steering wheel or pedal pulsation when braking, if it has deep wear grooves, a rusted edge lip, or a thickness below the minimum, which is usually stamped on the rotor edge.

Difficulty: Medium Time: 1-2 hours Steps: 17 Tools: Jack and jack stands, 17 mm lug wrench (or 19 mm, depending on the lug nut type), 13-18 mm sockets and wrenches for the caliper guide pins and bracket, hex bit or Torx bit for the guide pins (depending on caliper design), torque wrench, wire or a bracket to hang the caliper, wire brush, brake cleaner, copper grease for the guide pins, threadlocker (if needed)

Part

  • 🔩 Front ventilated brake rotors, set for both sides of the axle (diameter on the 1.6 16V is about 258 mm; confirm the exact size against the removed rotor). New front brake pads are recommended at the same time. I am not giving an exact OE part number for this trim so as not to risk an error. Search for "front ventilated brake rotor Renault Sandero II" and match the size of the rotor you removed

Step by step

17 steps
  1. Park the car on level ground, put it in gear, and chock the rear wheels. Loosen the lug nuts half a turn, raise the front of the car, support it on jack stands, and remove the wheel.
  2. Inspect the caliper and the brake hose. If the hose is cracked or chafed, replace it separately.
  3. Remove the two caliper guide pins (on the back side of the bracket). Do not press the brake pedal while the caliper is removed.
  4. Lift the caliper off the rotor and hang it from the spring or control arm with wire. The hose must not hang under load or become twisted. Do not open the brake system.
  5. Remove the pads. Note their positions, and the positions of the anti-squeal shims and springs.
  6. Remove the two bolts that secure the caliper bracket to the steering knuckle. They are tight, so use a long breaker bar. Remove the bracket.
  7. Remove the rotor from the hub. If it is stuck, tap it on its edge through a wooden block or treat it with penetrating oil. If the rotor has a retaining screw, remove it with an impact driver.
  8. Thoroughly clean the hub mounting surface with a wire brush to remove rust and scale. Any dirt will cause runout in the new rotor and vibration when braking.
  9. Degrease the new rotor with brake cleaner and remove the protective coating from the friction surfaces. Install the rotor on the hub.
  10. Clean the bracket and the pad seating areas, install the bracket, and tighten its mounting bolts to the manufacturer's specified torque. The torque for this part is high, around 100 N·m (74 lb-ft) or more; confirm the exact value in reference data for your trim. Use new bolts or threadlocker if required.
  11. Lubricate the caliper guide pins with suitable grease and check the boots. If a boot is torn or a pin sticks, replace it.
  12. Install the pads. If you are fitting new pads, push the caliper piston all the way back with a C-clamp or a special tool. Watch the fluid level in the reservoir: you can draw off a little excess beforehand to avoid overfilling.
  13. Fit the caliper and tighten the guide pins to the specified torque (usually about 25-35 N·m (18-26 lb-ft)).
  14. Repeat for the other side of the axle.
  15. Install the wheels and hand-tighten the nuts. Lower the car and tighten the nuts in a crisscross pattern with a torque wrench to the manufacturer's specified torque (for the Sandero II, usually about 100-110 N·m (74-81 lb-ft)).
  16. Before driving off, pump the brake pedal several times until it feels firm, and check the brake fluid level. Top up to the MAX mark if needed.
  17. Bedding-in: for the first 200-300 km, avoid hard braking. Perform 5-6 gentle decelerations from 60 to 20 km/h without coming to a full stop, to evenly mate the pads to the new rotors.

Common mistakes and warnings

  • Brakes are a safety system. If you have no experience working on brakes, have a repair shop do the job. Do not replace the rotor on only one side; always replace them in pairs. Do not touch the working surfaces of the rotors and pads with dirty or oily hands. After reassembly, always check the pedal: it should feel firm, without sinking, and the car must not pull to one side when braking. If you have any doubts, do not drive on the road.
