rafcapri wrote:Hi guys, my master and brake servo have seen better days. it's leaky at the seal, between the master and the servo, and more importantly there is no bite when I press the pedal when I stop at a light. it sinks into the floor slowly and I have to lift my feet up quickly and press it again to avoid hitting someone in front and Auckland is very hilly! Any idea what's causing this sinking feeling?
What specifically should I replace? Should I replace with factory parts from Tickover/Burton or find better ones/upgrade? If yes, where can I find better parts? Any links would be great. Does the brake fluid need to be completely full all the time since mine is leaky, it drops down often. And what DOT fluid should I use? Once I saw the plastic cap on the reservoir squirting fluid everytime I pressed the brake pedal, I fixed that with super glue - seems to improve the braking for a month before it started to be even worse than before.
I have changed front pads and rotor. I've not done the shoes at the back and I know it's high time, so will need to get that replaced very soon as well - Tickover has the right size which is 45mm.
Any input is appreciated.

If no pitting ( or other damage ) then go for the seal kit and bleed the brakes . If there is pitting then its reasonable to expect similar damage in the calipers and rear wheel cylinders as contaminated ( with water ) brake fluid is the cause and it usually starts at the master cyl and progresses thru the system , so you should at least check for further damage.
Part of the essence of classic motoring is that you fix this stuff yourself and on the scale of things a brake job is not a biggie , but if you need the car for work then having it off the road while you nut it out is out . Haynes manuals are about all you will find here. . A daily driver will be fine with the standard kit, but it still has to work
