Removal of early ALB-related parts
Blower unit removed
- To remove the three brake pipes that run behind the blower unit, you must first remove the blower unit itself.
The blower unit can be easily removed by disconnecting the connector and then removing the four fixing bolts on the top and bottom.
After removing the early ALB units.
- Next, remove the modulator, accumulator, and pump assembly along with their brackets.
Removing them without cutting the brake pipes would be difficult, so I cut them with clippers before removing them.
Removed early model ALB units

They consist of a modulator, accumulator, and pump assembly, so they are quite heavy.
The modulator bracket for the early-model ALB will be reused, so the fixed units need to be removed, but the pipe connecting the modulator and accumulator passes through a hole in the bracket, so the pipe needs to be separated.
Because this pipe is under high pressure, the service manual says to use a special tool to release the internal pressure and bleed it out through the bleeder plug before removing it.
I just cut it with clippers, but even though the cut end of the pipe looked crushed and blocked, brake fluid sprayed out in a mist for a while.
Installation of late-model ABS parts
After the brake pipe installation is complete
- On the back of the blower motor, three brake pipes, a vacuum pipe connected to the brake booster, and a clutch pipe (MT vehicles only) are bundled and secured with rubber clamps (rubber pipe clamps).
Even if the fixing bolts for the metal clamps (clamps, brake pipes) that secure the rubber clamps are not fully tightened, the brake pipes are held firmly in place by the rubber clamps, making it difficult to adjust their position by moving them from side to side.
Applying a lubricant such as CRC to the contact surface between the pipes and the rubber will make the pipes easier to move and adjust their position.
After the brake pipes and late-model modulators have been installed
- Compared to the earlier ALB model, the absence of an accumulator and pump assembly, along with the more compact modulator, results in a much cleaner appearance.
When installing the brake pipes, the modulator can be surprisingly inconvenient, so it's easier to install the modulator after laying out the brake pipes in a certain position.
Also, the most difficult pipe to install is the long pipe (pipe COMP.W, brake) connected to the left front brake (passenger side), so it's recommended to prioritize installing this pipe.
