Changing the brake hoses on Toyota Carina

Brake hoses are safety components. The hose must be checked for cracks. If the hose has cracks, it must be replaced!

The brake hoses are located on the brake circuit, most often there are 4 of them and they are located behind the wheels.

You will need a pipe wrench to remove your hoses. (See the 2 examples in the photo opposite).

When replacing the hoses, start with the one furthest from the master cylinder. (order: right rear wheel, then left, right front wheel and finally left front wheel).

Raise your vehicle safely (chop the opposite wheel, jack and axle stands).

You can take advantage of this intervention to change your brake fluid (to be changed every 2 years).

The brake fluid you are going to use must match the standard required by your vehicle (examples: DOT 3, DOT 4, DOT 5, etc.).

Locate your brake hose and fittings. Wire brush the fittings and use penetrating oil.

In order not to spill too much brake fluid on the ground and especially not to empty your filler bottle, it is best to pinch the hose. You can use special pliers or vice grips carefully.

Before dismantling, make sure that the new brake hose is identical to the one on your vehicle.

By using imperatively a pipe wrench of the correct size (otherwise the nut will be rounded off) remove the nut from the rigid pipe fitting.

Then remove the hose by removing its retaining clip.

Disassemble the second fitting to be able to disassemble your hose.

Reassemble your new hoses by tightening moderately rigid fittings. Always using the pipe wrench.

Reposition the staples and retaining devices.

By changing your hose you have introduced air into your hydraulic circuit, so you need to bleed it.

You should locate the brake fluid reservoir in the engine compartment.

Identify the min and max levels and fill your jar gradually to stay between these two levels.

An assistant should pump the brake pedal when you are going to operate the bleeder on your system.

The bleeder is located on the caliper or brake drum, it is very fragile and must be tightened moderately with a ring spanner.

Use a flexible hose to see the air bubbles coming out of the circuit. When there are no more you can move on to the next cylinder.

For bleeding, also proceed by starting with the cylinder furthest from the master cylinder, i.e. the rear wheel.

When you have finished changing and bleeding each hose, you must check that there is no air in the circuit: your brake pedal must not be molle and must not be able to touch the floor when you press down fully.

Reassemble your wheels, tighten them to the correct torque, and dispose of the waste at the recycling center (brake fluid, hoses, etc.).
