HYDROVAC:
After overhauling the master brake cylinder, the now higher pressure
was soon too much for the Hydrovac's servo cylinder. All brake fluid
eventually found its way into the Hydrovac. Instead of repairing, we
changed the complete Hydrovac unit (4535.21) for a good used one sourced
from Jörn Haarmann. I just cleaned and rust-proofed it to
keep its original appearance. The old servo will be overhauled and kept
as a spare.
When the brake fluid had emptyed into the Hydrovac, the brake warning light on the dashboard didn't came on. Definitely something you want to have with a single circuit brake system. So I replaced the shot "Nivocode" cap for a new one (4643.05). |

BRAKE
BALANCE VALVE: Another 404 weak spot (as on most cars with
a brake balance valve) - the valve seizes solid, causing the rear weels
to lock when brakeing hard. Unfortunately the balance valves 4861.05
are as rare as hens teeth. Finally 404-guru Jörn Haarmann
found an overhauled valve. It is important to fit a spacer (4875.01
for 0.5mm thickness, 4875.02 for 1.0mm) between valve and bracket for
the correct function of the regulation valve. Naturally the brake lines
where also seized in the valve body, so I made up new ones from original
PEUGEOT steel brake lines - after sourcing the (non-standard-these-days)
sockets from WÜRTH...

RADIATOR
I: The radiator was past its best, so I entrusted my local radiator
repair shop (Kühler Kneesch in Hamburg) to fit a new mesh.
The before/after photos show what a good job these guys did...

RADIATOR
II: The top tank of the radiator was polished again. I know
that this is not original (should be also black) but we like
it that way. At least the radiator itself is still the original one...

THERMOSTABLE
REAR BRAKES: While checking the brakes I found out that brake fluid
was sipping past the rear brake cylinder seals. Instead of overhauling
those, new ones were fitted (bought from Jörn, as you might
have guessed) along with some new springs for the brake shoes. Rust-proofing
was done with FERTAN (great stuff). As the front wheel cylinders
were already replaced when Karen purchased the car, the only
thing left do do was bleed the now completely renewed or overhauld brake
system.
Again the 404 is ready to be enjoyed this summer! |
