Brake overhaul booklet

Oetker · May 13, 2011, 08:06:30 PM

So far I opned 3 boosters and I found them all in good shape, rusted but seals were all perfect.
However they are best with some small maintenance..
Open them like this.

The only thing that we found bad in 3 boosters is the foam where air is sucked in.

Clean this parts and control for rips or wear.

Also the big rubber that seal the compleet booster need control.

You can cut a piece from whatever you can use as a filter.

Control Vacuum inlet valve for leaks.

However there are kits to be found (but difficult) for around €35.-, but the only thing you use is the foam and the seal.

After that a derust and spray, and it will look very nice.

If you happen to come across such a kit, let me know please

Hi Anders.

Look at this:
http://www.autopartswarehouse.com/sku/AP/Brake_Booster_Repair_Kit/W0133-1619446.html

Are boosters all the same size? this kit includes the main membrane.

Oetker · May 16, 2011, 07:49:04 PM

No, there are membranes that have have different sizes.
The Peugeot number for the original kit is 4599.21 but Peugeot dealers don't have this anymore
in the whole of Europe.

If i put this number in my parts-bible some numbers from Bosch and Renault come up.
It seams this kits are used in twingo's Berlingo's Clio's and a lot more.
This is not verified by me as correct.

If you want the original thing I have a German adress that have a load of old stock Peugeot parts.
I ordered mine there.

I did a search and came up with this interesting link:
http://www.recambiosviaweb.com/m93/d4685/c15769/l8442410/i162526/juego-de-reparacion-servofreno-renault-scenic-i-ja0-1-19-dti-ja1u-80cv.html

It is a Bosh PN: BOSCH 0 204 120 023

If that is the right part it is not expensive.

Looked them up on Google Earth. The address is:
Recambios Viaweb S.L.
Camino de Astigarraga,
2 Edificio oficinas Mamut,
planta 2,
oficina 8
20180 Oiartzun

Which is some miles outside San Sebastian in northern Spain.

It should be right, not verified by me because I found original, but why not drive to the local Renault dealer.
Renault price last year was €35

Oetker, how did you remove the fork assembly with the piston? It seems rather stuck in the black plastic tubing it sits in......

Oetker · June 21, 2011, 08:20:18 PM

The secret to remove is here.

RazorbackNOR · June 21, 2011, 09:16:58 PM

Okay....?

Checked in there now, none the wiser on how it should be taken apart thou.....

Oetker · June 21, 2011, 09:25:14 PM

It's been a while since I revived the thing, but as far as I can call back there is a metal plate that you can slid out.

RazorbackNOR · June 21, 2011, 09:44:14 PM

I do believe you mean the little metal plate in the middle of Anders' photo here.....

It ain't there on mine......

RazorbackNOR · July 17, 2011, 08:10:02 PM

Roy, on page 11 in the booklet, you say " use some brake grease around the inside of the rubber boot" On mine the boot was packed with, I guess, regular grease. Seemed to have done the job, still there and no leaking either inside or outside.

Should I buy enough to pack the boot full with brake grease, or would a regular type suffice? And would you recommend some on the inside, or packing it full?

suffolkpete · July 18, 2011, 08:39:29 AM

Under no circumstances should you use ordinary grease in place of brake grease as it will attack the rubber parts.

RazorbackNOR · July 18, 2011, 08:12:53 PM

It's cleaned out now, but doesn't seem to have damaged any of the rubber as far as I can see.
Filling the boot with brake grease won't be cheap...
