Tu Rear Drum Brake Force

[davemar 16]

The 205 1.1 failed it MOT, mainly brakes and a wheel bearing. The rears (drums) failed for being too weak, does anyone know what force the rears should be giving? The MOT place gave me readings of around 35 for the rears and 220ish for the fronts.

I think the rears should be giving more like 100+ the last time I had rear drums that bad (albeit on a 106) it was because both cylinders had started leaking slightly and I had fluid coating the braking surface..... worth a quick pop off with the drums to investigate me thinks!

It looks like one of the cylinders was leaking a little, didn't have time to check the other one.

 

I've got Girling drums, but am confused to which parts I need to replace these cylinders. Looking on servicebox, there's the 4402-73 and 4402-74 for left and right cylinders, or 4402-75 for (I assume) is non-sided cylinders. Which do I need, and how do I tell them apart?

The Base model vehicles don't have an inline brake pressure regulator like the GTi and Euro Rallye variants (as well as some Diesel/Turbo Diesel models)

On the note of brake shoes, I tried to get some for a 1.6 gti beam (girling) from peugeot today and they were no longer available!

Thanks for the confirmation welshpug, I've ordered some new ones now.

 

When I was dismantling the brake to inspect them, when I put them back together the brake is now completely slack. I did remember to clip the cable back on to the lever. Are the auto-adjuster things supposed to spread themselves out when you press the pedal until they reach some settling point?

 

There's a lot to be said for a transparent drum to see whats going on!
