How to Replace the Front Brake Pads on a Citroën Picasso

Replacing the front brake pads on a Citroën Picasso is a manageable task for those with some mechanical know-how and the right tools. This guide will walk you through the process step by step, ensuring your brakes are replaced safely and efficiently. Always consult your car’s manual for specific instructions or seek professional assistance if you’re unsure.

Tools and Materials You’ll Need

Before you begin, gather the following tools and materials:

• Jack and Jack Stands: To safely lift and secure the car.
• Wheel Wrench: To remove the wheel nuts.
• Brake Pad Replacement Kit: Includes new brake pads compatible with your Picasso.
• Socket Set: For removing bolts.
• Torque Wrench: To properly tighten bolts to manufacturer specifications.
• C-Clamp or Brake Caliper Tool: For compressing the brake caliper piston.
• Screwdrivers (Flathead and Phillips): Useful for prying or holding components.
• Brake Cleaner: To clean components during the process.
• Anti-Squeal Grease: To prevent brake noise.
• Disposable Gloves: To protect your hands from dirt and chemicals.
• Eye Protection: To shield your eyes from dust or debris.

Step-by-Step Guide

Step 1: Prepare the Vehicle

1. Park on a Level Surface:
   • Ensure the car is parked on a flat, stable surface.
   • Engage the parking brake and place wheel chocks behind the rear wheels.
2. Loosen the Wheel Nuts:
   • Slightly loosen the wheel nuts on the front wheels before jacking up the car. Do not fully remove them yet.
3. Lift the Car:
   • Use a jack to lift the front of the car.
   • Place jack stands securely under the car to ensure stability. Never rely solely on the jack for support.
4. Remove the Wheels:
   • Fully unscrew the loosened nuts and remove the front wheels, exposing the brake assembly.

Step 2: Access the Brake Pads

1. Inspect the Brake Assembly:
   • Take note of the brake caliper, brake pads, and rotor.
   • Check for any visible damage to the rotor or other components.
2. Remove the Caliper Bolts:
   • Locate the bolts or guide pins securing the brake caliper.
   • Use the appropriate socket or wrench to unscrew them.
3. Lift the Brake Caliper:
   • Carefully lift the caliper away from the brake pads and rotor.
   • Important: Do not let the caliper dangle by the brake hose; use a bungee cord or hook to secure it to the suspension.

Step 3: Remove the Old Brake Pads

1. Slide Out the Brake Pads:
   • Gently slide the old brake pads out of their mounting brackets.
   • Note how the pads are positioned, as the new pads must be installed in the same orientation.
2. Inspect the Brake Components:
   • Examine the rotor for grooves or damage. If the rotor is severely worn, consider replacing or resurfacing it.

Step 4: Prepare for Installation of New Pads

1. Clean the Brake Components:
   • Use brake cleaner to remove dust, dirt, and grease from the caliper and rotor.
2. Compress the Caliper Piston:
   • Use a C-clamp or brake caliper tool to gently push the caliper piston back into its housing.
   • Tip: Open the brake fluid reservoir under the bonnet slightly to relieve pressure. Check fluid levels after compressing the piston.

Step 5: Install the New Brake Pads

1. Apply Anti-Squeal Grease:
   • Apply a thin layer of anti-squeal grease to the back of the new brake pads. Do not get grease on the pad surface or rotor.
2. Position the New Pads:
   • Slide the new brake pads into the mounting brackets, ensuring they sit securely in place.

Step 6: Reassemble the Brake System

1. Reattach the Caliper:
   • Carefully place the caliper back over the new brake pads and rotor.
   • Reinsert and tighten the caliper bolts or guide pins.
2. Torque to Specifications:
   • Use a torque wrench to tighten the bolts to the specifications in your Citroën Picasso’s manual.

Step 7: Reinstall the Wheels and Lower the Car

1. Reattach the Wheels:
   • Place the wheels back on the hubs and hand-tighten the nuts.
2. Lower the Car:
   • Use the jack to lift the car slightly, remove the jack stands, and lower the car to the ground.
3. Fully Tighten the Wheel Nuts:
   • Use a torque wrench to tighten the nuts in a star pattern to ensure even pressure.

Step 8: Final Checks

1. Pump the Brake Pedal:
   • Press the brake pedal several times to seat the new pads against the rotor.
2. Check the Brake Fluid Level:
   • Top up the brake fluid if necessary and close the reservoir cap.
3. Test Drive:
   • Carefully test the brakes in a safe area to ensure they’re functioning correctly.

• Don’t Rush: Take your time to ensure everything is installed correctly.
• Dispose of Old Pads Properly: Brake pads contain hazardous materials; recycle them responsibly.
• Professional Help: If you’re unsure about any step, consult a professional mechanic.
