Having overhauled the front callipers with new seals, pistons, similar attention to the servo/slave cylinder and fitting of a new master cylinder I find that the front brakes lock up when I connect the vacuum hose to the servo. Without this the brakes release and wheels run free. I've stripped and checked all components three times now but to no avail. It seems like there is a build up of air pressure without it being vented. Have checked valve on slave cylinder and this is not stuck and appears to move freely. Last dismantle and further detailed inspection however I noticed 'pushrod' within slave cylinder had a tapered end unlike the flush end shown in repair manual. The one fitted to my single line system seems to resemble the type fitted to the dual system, again as shown in the repair manual. Could it be that my servo in a previous life has been built using an amalgam of different fittings and thus fails to work properly?
I'm at the end of my tether and would welcome any views on prognosis before biting the bullet and investing in a replacement servo.
Who offers best service for this?
Any help / avice would be greatly appreciated.
