rear brake pressure regulator on 405 estate

Caveman_si 13 April 2005 23:18:54
 I need a spring for a rear brake pressure regulator for 405 estate (m
reg). (with abs if that makes a difference)

I just want the spring not the whole unit as the nice man from peugeot
says it ВЈ73 +vat

I have been reliably informed that there is a comparable spring on a
citroen but no idea which one. And id be happy for one of those too.

does anyone know where i can get a new one cheap??? i dont fancy
climbing round the scrapy in this weather.

cheers si

The 405 shares it's floorpan with the BX, but that doesn't have a rear
regulator, using it's hydraulic, (olio-pneumatic?) rear suspension pressure
to do the same job.

I'd cruise the scrap-yards looking for one on a 405 estate, as the saloon
may have a different loading.

They were only fitted to estates. ABS made no difference. I had the
same problem on my old 405 a couple of years ago. Went to the scrappy
and got one for nothing--so to speak!!

 cheers guys just didnt fancy the day at the scrappy but looks like its
only way.

ON another note does anyone know what the rear brake pressure regulator
actually does? To me it looks like it connects the suspension to the
abs braking system but no idea why?

cheers simon

 The rear brake pressure regulator is there to adjust the amount of braking
effort applied to the rear brakes depending on the load the vehicle is
carrying.
The purpose of the spring is to apply the force to move the regulator valve.
Once the valve has moved further movement of the suspension could cause the
link to snap if it was just a rod hence a spring. You can use any spring
that is the length to just be in tension between the unit and the suspension
under no load and of the same gauge. It is possible to braze a piece of wire
on the replace the broken part of the spring. This is usually the hook at
the suspension end. You could try going to your friendly Peugeot spares
dealer and asking to measure the spring. I guess this is not possible as
most parts for Peugeots seem to be special order these days. The 406 is also
fitted with a similar device.

 Hi

What is basicly does is control the amount of braking force to the rear
wheels depending on the load on the rear suspension.

If the boot is empty then the rear of the car will be lighter & the rear
wheels will be more prone to locking, When the suspension at the rear rises
because the front has dropped as the brakes are slammed on the valve
reduces the flow of brake fluid to the rear & helps stop the wheels locking
up.

If the boot is loaded up with stuff then the rear of the car will be lower,
The valve will now let more fluid flow to the rear wheels because theres
more weight over the back wheels & theres less chance of them locking.

Hope that helps explain things clearer.

It has nothing to do with the ABS as such. It regulates the amount of
pressure needed to work the back brakes in accordance with the amount
of load in the back of the car. The more load in the back the more
"power" to the rear brakes.
