"Aviation style" brake hoses - 7 hose kit: stainless steel braided hose with PTFE Teflon coated inner.

This type of hose offers improved braking efficiency and reduces power drop thanks to stainless steel braiding that prevents hose dilation.

These hoses are available in different lengths:

7 cm (JKD1015)

10 cm, with ABS (JKD1019)

10 cm, without ABS (JKD1033)

This article is not so much about tips and advice, but aims to show you just how easy they are to fit!

On my Patrol Y61 Sport, without ABS, there are only 6 original Nissan hoses to change.

If you have ABS there's one more hose and so the Goodridge Kit contains 7 hoses.

Please note that in the case of my Patrol Y61 3.0 Sport model (in other words, without ABS), I needed to modify the hose above the front axle because there were not enough points to attach the rigid pipes.

On a luxury model (therefore with ABS), the kit fits perfectly as is.

Here's the part supplied in the Goodridge Kit that wouldn't fit on the Patrol Y61 3.0 Sport model:

Hose above the front axle

Front wheel hoses

Rear wheel hoses

Hose above rear axle

Dismantling the hoses and fitting the Goodridge set really is straightforward.

With the Goodridge hoses fitted:

Front wheels

Rear wheels

The hose above the rear axle

The hose above the front axle

An explanation on how to bleed the system once the new hoses are fitted and properly tightened don't forget to double check!

Be sure to clean the parts if you've managed to smear any brake fluid or degreasing agent...

Bleeding the brake system

IMPORTANT

Whilst bleeding, keep an eye on brake fluid level in the master cylinder

If you think there might be any air in the master cylinder then bleed it.

Fill the brake fluid reservoir with new "DOT 3" fluid and make sure there is plenty whilst bleeding the brake circuit.

Place a container under the master cylinder reservoir to catch any brake fluid spillage

On ABS models, ensure that the ignition key is in the "OFF" position, disconnect the ABS controller connections and the earth cable on the battery.

Bleed out air as follows:

1) LSV (Load sensing valve) bleed nozzle

2) Back left brake

3) Back right brake

4) Front left brake

5) Front right brake

1) Attach a transparent plastic pipe to the bleed nozzle
2) Depress the brake pedal fully and repeat a number of times.
3) Keeping the pedal fully depressed, loosen the bleed nozzle to release any air.
4) Close the bleed nozzle.
5) Release the brake pedal slowly.
6) Repeat steps 2. to 5. as above until clear brake fluid with no bubbles flows from the bleed nozzle.
7) Tighten the bleed nozzle.

Torque: 7 to 9 Nm (0.7 to 0.9 kg-m)

Master cylinder bleeding

1) Fill the reservoir with new brake fluid.
2) Using your fingers, block all the openings on the master cylinder to prevent air being drawn in as the pedal is released.
3) Ask your assistant to gently depress the brake pedal a number of times until no more air escapes from the master cylinder.
4) Refit the brake pipes to the master cylinder. Tighten the flare nuts.
5) Torque: 15 to 17 Nm (1,5 to 1,7 kg-m).
6) Bleed the circuit. Refer to "Bleeding the brake system".

The brake pedal will feel more effective. To further improve braking you can fit DBA slotted and punched discs:

Front: JDR1001

Rear: JDR1002
