Brake OH 03, ABS

Rate this Entry



After looking at the state of the brake caliper, couldn’t trust the master cyl
so decided to replace it.



Already slowly leaking.
It’s AT model so the driver will be using the brake more than the MT owners.



Pushrod clearance checked.



Unlike the CL master cyl that has single piston, BR one has two pistons for
the tandem hyd system.
Therefore, it is highly recommended to bench bleeding it before
installing it on the car.
Otherwise, you are going to spend/waste lots of time and fluid for
bleeding the system.



Now installed on the car and 1st round of pressure bleeding in progress.



In order to leave enough time before starting the 2nd round of
pressure bleeding, started working on the ABS.

The owner never exercised the ABS in the past and as expected based on
the result from initial test driving session, ABS accumulator fluid was full of air.

As I was worried about the state of the solenoids, decided to flush the system
extra two times.



It’s not easy to lock all four wheels at the same time so always best to
manually activate each solenoid.
You can also visually see/feel the leaky solenoid using this method.



Cleaned the reservoir to this level.


****** Message to the owner ******
All four solenoids functionality were recovered and at this stage,
they were not leaking or stuck closed so I hope you will start exercising
the ABS from now on.
Before the tyre warms up, please just apply full brake from about 15mph
when/where it is safe to do so.
This will keep your ABS healthy until next time you flush the system.





2nd BR bleeding completed, pressure kept on the system for
about 30min in order to check for any leakage, parking brake adjusted,
fluid level adjusted.

ABS service finished and will adjust the fluid level after the test driving session.


Done.
