Brake Hose - Rear

Replace the rear brake hose connecting the brake line to the caliper, including bleeding the brake system to restore proper hydraulic function.

Warnings

Tools required

Parts

• Rear brake hose × 1 — Use OEM Toyota part number
• Brake hose banjo bolt copper washers × 2 — Two washers per banjo bolt
• DOT 3 brake fluid × 1 — Toyota Genuine or equivalent

Fluids

• DOT 3 Brake Fluid — 0.25 qt

Preparation

1. Park vehicle on level surface and set parking brake
2. Place wheel chocks in front of front wheels
3. Loosen rear wheel lug nuts while vehicle is on ground (do not remove)
4. Raise rear of vehicle with floor jack and support securely on jack stands rated for vehicle weight
5. Remove rear wheel on side being serviced
6. Clean brake hose connections with brake parts cleaner to prevent contamination
7. Place drip pan under work area to catch brake fluid
8. Open master cylinder reservoir cap to allow easier fluid flow during hose removal

Procedure

1. 1

   Remove brake hose from caliper
   Locate the banjo bolt connecting the brake hose to the rear caliper. Using a 14mm box wrench, carefully loosen and remove the banjo bolt. Be prepared for brake fluid to drain. Remove the bolt completely along with the two copper crush washers (one on each side of the hose fitting). Immediately plug the caliper port with a clean rag to minimize fluid loss.
   ⚠Brake fluid will drain from both the hose and caliper. Have drip pan positioned to catch fluid.
2. 2

   Remove brake hose from bracket
   Locate the brake hose bracket mounted to the vehicle body or suspension component. This clip-style bracket holds the hose in position. Remove the retaining clip or fastener securing the hose to the bracket. On some configurations, this may be a bolt that requires a 10mm wrench; on others it is a spring clip that can be removed by hand or with pliers.
3. 3

   Disconnect brake hose from hard line
   Using a flare nut wrench (10mm), carefully loosen the fitting connecting the flexible brake hose to the metal brake line. Use a backup wrench on the hose-side fitting to prevent twisting the hose. Once loose, unthread the fitting by hand and separate the hose from the line. Allow fluid to drain into the drip pan. Plug the hard line with a rubber cap or clean rag to prevent contamination.
   ⚠Use a flare nut wrench (not a standard open-end wrench) to avoid rounding off the soft brass fitting.
4. 4

   Remove old brake hose
   Remove the old brake hose completely from the vehicle. Inspect the mounting bracket and hard line threads for damage, corrosion, or debris. Clean the hard line fitting threads with a clean rag. Verify the replacement hose matches the original in length and fitting configuration before proceeding.
5. 5

   Install new brake hose to hard line
   Thread the new brake hose onto the metal brake line fitting by hand until snug. Ensure the hose is not twisted and routes naturally without tension. Using a flare nut wrench and backup wrench, tighten the line fitting to specification. Verify the hose positioning allows full suspension travel without binding or stretching.

6. 6

   Install brake hose to bracket
   Route the brake hose through the mounting bracket and secure it with the retaining clip or bolt. If using a bolt, torque to specification. Ensure the hose is properly seated in the bracket and positioned to prevent rubbing against suspension components or the tire during operation.

7. 7

   Connect brake hose to caliper
   Install two NEW copper crush washers onto the banjo bolt (one on each side of the hose banjo fitting). Position the hose banjo fitting onto the caliper inlet port, ensuring proper alignment. Insert the banjo bolt through the fitting and thread it into the caliper by hand. Verify the hose is not twisted and has clearance for wheel movement. Torque the banjo bolt to specification using a torque wrench.
   ⚠️Must use NEW copper washers. Never reuse old washers or leaks will occur.

   Refill master cylinder reservoir
   Check the brake fluid level in the master cylinder reservoir under the hood. Add fresh DOT 3 brake fluid from a sealed container to bring the level to the MAX line. Keep the reservoir filled throughout the bleeding process.
9. 9

   Bleed rear brake caliper
   Attach a clear plastic hose to the caliper bleeder screw and place the other end in a container partially filled with brake fluid. Have an assistant pump the brake pedal 3-4 times and hold pressure. Open the bleeder screw 1/4 turn using an 8mm wrench. Fluid and air will flow into the hose. Close the bleeder screw before the pedal reaches the floor. Repeat this process until no air bubbles appear in the clear hose and only clean fluid flows. Check and refill the master cylinder reservoir frequently during bleeding.
   ⚠Never let master cylinder run dry or the entire system will require bleeding.

    Final inspection and wheel installation
    Inspect all brake hose connections for leaks. Wipe connections clean and look for fresh fluid seepage. Verify the brake hose routing has adequate clearance and is not twisted. Reinstall the rear wheel and hand-tighten lug nuts in a star pattern. Lower the vehicle until the tire just contacts the ground. Torque lug nuts to specification in a star pattern using a torque wrench. Lower vehicle completely and remove jack stands.

Reassembly

1. Close master cylinder reservoir cap securely
2. Clean any spilled brake fluid from brake components and suspension with water
3. Verify brake pedal feels firm before starting engine (pump pedal several times)
4. With engine running, verify brake pedal height is normal and pedal does not sink

Verification

• Pump brake pedal firmly several times - pedal should build to firm pressure and hold steady
• With engine running, apply firm brake pressure for 30 seconds - pedal should not sink
• Inspect all brake hose connections for leaks while assistant applies brake pressure
• Test drive in safe area at low speed (under 15 mph) to verify normal brake operation
• Perform several moderate brake applications to verify proper braking response
• After test drive, re-inspect all connections for leaks with vehicle warm
• Check master cylinder fluid level and top off if needed to MAX line
• Verify brake warning light is not illuminated on instrument cluster
