MG MGA - new servo problem

HI all mga people , i have just fitted a new powertune servo , run the motor , brakes lock up & will not come off until you remove the filter & gently open the valve , i have re- read the instructions & cant find where i may have gone wrong ?? please help as i am stuck just like the mga.

sounds like a fualty unit to me,something acting like a none return valve that should'nt, i would return it for an exchange if thats pos.

thanks for reply , after more trying i have come to the same conclusion ! & am waiting for MOSS to come back ?. We are going to France & Switzerland next week with our club (CBCCC)devon , check it out good sight , i thought that it would be good to uprate the brakes before the trip as there are some very steep hills on the passes!!!

You shouldn't need a servo here, even in fairly spirited driving. Just keep to the old rule of using same gear down the hill that you would use to go up it and let the engine braking take the pressure off the brakes.

The issue is mostly brake fade from overheated brakes, not that the original system isn't up to the job of stopping the car.

Having a servo will not have any effect of the brake temperature and brake fade if you are on the brake all the way down the hill.....

Dominic, thanks for the interest sadly i am now 15 years older than the car & i think that the car is in better condition as it has had the usual rebuild etc but gladly i have not ! so i look to make life a little easier , the problem is not the car or me but other motorists who have not driven older cars & insist on over taking & taking the safety margin that i try to maintain,i feel that we drive for the other motorists most of the time.{Beatenburg}is our destination for 12 nights with our motor club from Devon,{cbccc} we intend to do some of the passes that we have not used before , also spend some time on the trains etc, where are you in Switzerland ?? are you near ? if so come & have a beer!!!
