Brakes locking on (6 replies)

After the short drive to the local garage for the MOT, the brakes were locked solid, cracking the joint on the front of the servo released the pressure. Back home, I suspected the servo's air release valve but after cleaning that and replacing the seal, the problem still persisted. The main piston moved up and down the bore with its new seals and the diaphram was new.

Out of ideas I decided to replace the servo, after hearing horror stories of new units failing, I rang David Kingerley of Classic Car Spares (01332 873685) to see if he would take a look at the unit and refurbish if required. Instead, he supplied a fully reconditioned original servo which has had the bore sleeved with stainless and is guaranteed to work at £235 exchange, much better than the £400 for a new one.

Now fitted the problem has gone - MOT tomorrow hopefully

That looks to be a good deal for those with faulty or suspect servos.  Can you post a photo of the servo so that we can see what sort of finish Classic Car Spares turn out on these restored units as what they look like is also important to some?

Well, with a coat of black paint on the shaft it would look much better and more like an original one.

Do you mean the cylinder body Robert, this was bare metal on the original

Yes, it should be dull cast iron - which soon rusts, so is generally painted black but not alloy silver.

Here's mine I had refurbed.  The coated the cast iron bit to try and match the original look
