16v brakes

[macc nova]

Yesterday i changed my brake pads and since then i have noticed when i brake they lock up alot easier! (there is hardly any travel on the pedal)!

A couple of weeks ago i had to change the non return valve as it was buggered, but the servo seems to be ok! :thumb:
What do you recon could be the problem? Rear drums in need of refurb? Dodgy pressure regulating valves? servo/mc?

Which end is locking up

[macc nova]

the rear

???

Does sound like the regulating valves to me.
As the rears shouldn't get enough brake pressure to lock up...

[macc nova]

thats what i was thinking, the fronts lock up aswell but you can feel the rears lock up first

[macc nova]

just been on the phone to vauxhall and apparently the pressure regulating valves for nova's are nls? where else could i get some from?

Scrappy.
Off here/mig?

I had a rear wheel cylinder fail on my GSi & that was making the rear shoes lock up on one side. Drum was full of fluid too.

im gonna be taking both apart for a full inspection at the weekend, so i can see what the problem is!

Right then! this morning i took off both rear drums to inspect the problem, apart from alot of dust there didnt seem to be a problem. i have taken photos of them but i am unable to upload them as my computer is fooked! One shoe looked to be abit glazed but thats about it. Just wondering whats the minimum size that the shoes should before they need changing? Cheers
