1972 Suffix A.

I thought I would try and push out the brake caliper pistons to have a look at them to see if I needed to get them refurbished so I thought bleed the system (after both hubs being off) and off I go !! How wrong I was I couldn't bleed them so I traced back to how far the fluid was getting and basically its getting stuck at the start of all four flexible hoses to the caliper so I thought I would take one off and have a look.

My question is all pipes appear to have "something" metal the same distance from the end so does the fluid pass around/through something? ( It sounds metal if touched with small screwdriver)
If all four are blocked it there a way of clearing the blockage or have the walls given way and I should bin them and start again.

Car was sat for ten years before I got it so no idea when the brakes last worked.

Cheers and hope this make sense.

Flexis do swell internally over time and block. Change them.

I will change them due to age but I just wanted to understand if they where supposed to be clear straight through or have some kind of insert in them as they are all the same.
Thanks for your help .

Some but not all may have a plastic liner inside the rubber. Normally the only metal in a flexi is the metal nipple that supports the crimp on the unions at either end.

Ah yes and possibly a smaller diameter hole than at the inlet of the pipe. Thank you for shedding some light on that it was driving me mad. They look like they are original ones so they've last well but funny that all four front are blocked solid
 
Take the calipers off while you change the flexies, it's easy to blow the pistons out with an air line if they are not seized. Cover with a rag and keep your fingers out of the way.;):)

That's a good idea as it means I could be looking at the condition of them whilst I wait for new pipes. Last time I had some brake callipers refurbished rather than doing it myself and buying new pistons etc it was just as cheap to send them to Bigg Red they did a great job on my jag callipers

I don't think new callipers are that expensive, factor in the cost of plasters.:)
