They can be adjusted, at 60mm probably to its fullest extent. Get under the car and you'll see how it works and what needs doing. Its only one nut holds the adjuster.

Make sure to test as well, in a big empty car park.

mine aint got 1

mist be stuck in the normal position id get it checked mate coz if it frees off n 1 wet day itl spinn you round

as far as i know mines never beeen adjusted at all and its lowered 60mm! doesnt lock up or anything tho

yes mate i droped mine 50mm and got away with just setting it to the extent of the adjustment and it brakes ok but 60 you probs will hav to make the plates up like in the max haynes easy to do tho i just dident coz i was limitted to time @work:thumbs:

Just loosen it then slacken the spring totally, then tighten it.

I am lowering my car by 60mm, in the Max power haynes manual for a corsa it says that the rear brake pressure regulator will need to be adjusted.

Does this need to be done??

Does any firm produce whats known as a brake compensator for lowered suspension?
