Why not simply re-seal all 4 calipers?
Not too difficult and certainly cheap to get the parts, fresh hoses takes away any other doubt at the same time, just do the whole system at the same time.?
You have done the awkward expensive bit with the Master.
As to pads, I have never had a good response with Green Stuff etc products.
The subject is very subjective just like "what is the best oil" etc.
It is hard to get an early car to stop well and you need good brakes in today's world.
My opinion is to buy 'Carbone' and fit new discs at the same time to get the very best out of the system.
They can be a bit noisy in use, but do work well from cold, mighty expensive though.
The whole refresh is not cheap, but you will have the best brakes possible with 'stock' parts and cheaper than specialist calipers.
Let us know how you get on.
The flexible brake pipes are like fuel lines. If you can’t remember when they were last changed, or you don’t know, it’s a good idea to change them.
Once you have all the callipers on the bench and the pistons blown out, it is actually not that much more work to split them and have them media blasted and re-plated. Costs for plating all 4 were £50 three years ago and the result is very appealing I think. Only thing to bear in mind is that one of the bolts that hold the rear calliper together is NLA, so need to be careful not to damage the heads. The small o ring seals between the calliper halves and the spacers were a bit tricky to find at the time, but seem now in stock with various Porsche specialists.
Once you get them rebuilt it’s worth considering some simple maintenance to reduce the chance of them sticking due to lack of use. Once a year a get mine up on axle stands, wheels off, pads out and use this simple tool to fully depress the pistons a couple of time to exercise the full sweep. Rebuilt mine 11 years ago and still going well. https://www.ebay.co.uk/p/Silverline-Too ... gIYVfD_BwE
So brake calipers are all back from classic automotive, have installed them with new pads all round. Didn't buy EBC, as recommended, so thought I'd give some brembos a go as saw them on the type911 website. Have done about 100/150 km now without braking too hard to give the brakes time to bed in. Glad to say the car pulling to one side issue has been resolved. Still getting a bit of noise when braking, i'm guessing this is normal and part of the bedding in process ? Although, there seems to be a bit of noise coming from the front left wheel even when not braking. When i took the wheel off and turned it myself there seems to be a high spot which is catching but the discs seem in fairly good nick. I'm assuming this should sort itself over time ? Let me know your thoughts, cheers.
IMHO time to continue the bedding in and then drive the car normally.
It stops, it does it without drama, presume the pedal is nice and firm and consistent in it's position, so as good as the system gets.
As confidence grows it will become a memory.
Enjoy the summer drives!

I think everyone has different views of bedding in and running in routines.
I thought the idea was to get the brakes nice and hot and then let them cool, then you are done.
So in my race car I generally do a lap with harder and harder braking, and doing some left foot braking with the throttle on to get them nice and hot. Then do a couple of laps with as close to no braking as possible to cool them down and off we go.
Give the brakes some proper use and see how they go would be my advice.
sounds like a plan
