Today at Atelier Kaz - ex-Honda R&D, F1, Indy/CART engineer

This time, we are going to replace the master cyl and the brake lines.

Considering the unknown state of the master cyl, decided to replace it rather than
overhauling it.

Thank you to continuous support from Goodridge for the custom made brake lines
using the NSXCB special parts no..
Details are covered in here;

Please note that this parts no. is only recognised by the Goodridge UK and
at the time of writing, they will only take the order for delivery address within UK.





Many NSX with aftermarket brake line showed installation issue and some of them were
dangerously scratching against the chassis due to twisted line or wrong spec.

Once you have torqued the banjo bolt side, it is always a good idea to mark
the brake line against a reference point on the chassis so that you won’t
twist it while tightening the pipe fitting.








Front side installed with two line locators.
Off-the-shelf Goodridge product for NSX will only have one line locator which may
cause trouble if you are using the OEM damper.







Rear side installed. Not easy to see in this photo but moved the rubber protector
inside the hub carrier from the original brake line.

Same procedure in order not to twist the line.

Most of the off-the-shelf Goodridge product for NSX is designed for the early model
which has smaller calliper than the later spec one.
Therefore, if you have the later spec calliper, the brake line length may not be long
enough under the full droop depending on the chassis setup.





So, brake lines are now installed and time to bench bleed the master cyl.
This master cyl is brand new so I prefer bench bleeding it first before installing
it on the car to save some time and fluid.




Although the original master cyl looked to be the one from the factory, I have no idea
on what was done to the brake pedal pushrod in the past so always double check the
clearance under the specified vacuum pressure.






Pressure bleeding the entire brake system.
This NSX is equipped with the later spec ABS so start from the front callipers.


1st bleeding session has completed, left it for a few hours and then carried out
the 2nd round.
Applied small brake pressure and checked the friction level at the front.
No obvious difference between the R & L at this stage so will check it again
during the test driving session.
Also, will apply some hard braking to scrape off the rust from the inward disc surface.

Will keep the chassis on the lift overnight to make sure there is no leakage from the system.




Done.
