- Clean the brake master cylinder brake master cylinder reservoir, brake line connections and reservoir cap.
- Inspect the brake fluid for the following conditions, indicating brake fluid contamination:
- Inspect the master cylinder reservoir cap diaphragm and the reservoir-to-master cylinder grommets for swelling, indicating brake fluid contamination.
- If the brake fluid WAS contaminated with an oil-based or a silicone-based substance, indicated by fluid separation and/or a swollen master cylinder reservoir cap diaphragm and/or swollen reservoir to master cylinder grommets, perform the following:
- If the brake fluid WAS NOT contaminated with an oil-based or a silicone-based substance, but was contaminated with water or dirt, rust, corrosion, and/or brake dust, replace the brake master cylinder reservoir cap diaphragm.
- Place a clean suitable container under the master cylinder.
- Disconnect brake lines (3) from the master cylinder (1), then remove master cylinder reservoir cap (2).
- Allow the master cylinder (1) to drain into the container until empty.
- Install the brake lines (3) to master cylinder (1).
- Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.
- Remove all the wheels. Refer to Tire and Wheel Removal and Installation.
- Loosen the left[dash ]side front brake calliper bleed screw (2).
- Remove the left[dash ]side front brake calliper anchor plate to knuckle retaining bolts (4).
- Detach the brake calliper (1) from the knuckle (3).
- Suspend the brake calliper (1) upside down with heavy mechanics wire or equivalent.
- Remove the bleed screw (2) to drain contents of the brake calliper (1) into suitable receptacle.
- Tighten the bleed screw (2) and reinstall the brake calliper (1) to the knuckle (3).
- Install the NEW brake calliper anchor plate to knuckle retaining bolts (4).
- Repeat steps 12[dash ]18 for the right hand front brake calliper.
- Repeat steps 12-17 for the rear brake calliper assemblies.
- Install the rear brake calliper to knuckle with NEW retaining bolts.
- Bleed brake system. Hydraulic Brake System Bleeding.
- Install the wheels. Refer to Tire and Wheel Removal and Installation.
- Lower the vehicle to the ground.
Caution: Refer to Brake Dust Caution in the Preface section.
Caution: Refer to Brake Fluid Caution in the Preface section.
Caution: Refer to Brake Fluid Irritant Caution in the Preface section.
Notice: Refer to Adding Fluid to the Brake System Notice in the Preface section.
Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in the Preface section.
| • | Fluid separation indicates 2 types of fluid are present. A substance other than the recommended brake fluid has been introduced into the brake hydraulic system. |
| - | Swirled appearance = oil-based substance. |
| - | Layered appearance = silicone-based substance. |
| • | Fluid discolouration, indicating the presence of moisture or particles that have been introduced into the brake hydraulic system. |
| - | Cloudy appearance = moisture. |
| - | Dark appearance/suspended particles in fluid = dirt, rust, corrosion and/or brake dust. |
| 4.1. | Remove ALL of the following components listed from the vehicle. Each component contains internal rubber seals/linings which have been contaminated by the contaminated brake fluid in the brake hydraulic system. |
Refer to the procedures indicated:
| 4.2. | Clean out all the hydraulic brake pipes using denatured alcohol, or equivalent. |
| 4.3. | Dry the brake pipes using non-lubricated, filtered air. |
| 4.4. | Replace ALL of the following components listed and install them to the vehicle. Each component contains internal rubber seals/linings which have been contaminated by the contaminated brake fluid in the brake hydraulic system. |
Refer to the procedures indicated:
| • | Replace the brake master cylinder reservoir cap diaphragm. |
Notice: Refer to Fastener Notice in the Preface section.
Tighten
Tighten the brake pipe fitting to 15 Nm (11 lb ft).
Caution: Refer to Safety Glasses Caution in the Preface section.
Caution: Refer to Vehicle Lifting Caution in the Preface section.
Important: Bolts with micro-encapsulated thread sealant must be replaced after removal.
Discard the bolts.
Notice: Support the brake caliper with heavy mechanic wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.
Notice: Refer to Fastener Notice in the Preface section.
Tighten
Tighten the front brake calliper anchor plate bolt
to 60 Nm +120° (44 lb ft +120°).
Tighten
Tighten the bolts to 110 Nm (81 lb ft).
