I will be going to the post office tomorrow to get my free road tax and get the log book changed to Historic on my 1980 Spitfire. The dvla shows the production date as Dec 31st. But I have a heritage certificate which says Mar 23rd 1980. Do I need to send that off separately to get that changed or will the post office send it off with the log book to the dvla. Danny

Yeah that makes sense. I have also noticed it only happens on choke. When warm it is very slight and would not be niticed.  Just got to keep on bleeding I suppose to get firm up the pedal.  Danny

I have just noticed with the engine ticking over, if I pump my brake pedal the engine speed will. Rise a few hundred revs and dies down when I release the pedal. Is this normal, I can't say I've noticed it before.  I have can't get a hard pedal after bleeding the brakes three times.  Danny  

Ok I took the master off and gave it a good clean. Couldn't check the seals as it looks like it's unserviceable. There seems no way of getting the piston out.  Put it back and bled the system and all works fine. I will now get the servo back on and report back.  The only thing I can think of is some time ago I put adjustable operating rods on the clutch and brake to take  up any slack. I have now put the original one back on the brake. Although it all looked OK maybe this was not releasing properly and held pressure on the master,  who knows.  Danny

Thanks Rob,  I will strip it first and see if there is something obvious as you say.  WWatch this space 😊

Ok I've bit the bullet and taken the servo out, then made a connection between the two brake pipes. Bleed the front brakes only a they stick on after pumping the pedal, not as solid as before but then there is probably still some air in the system. Ondo bleed on calaper and all free up.  Funny thing is as I'm bleeding the brakes using a one way valve the pedal sometimes went hard. So not sure to buy a new master or try a rebuild kit.  Danny

That is interesting.. I will read it again later but it does seem the same. Next job I suppose is take the servo off and connect a new brake pipe between master and union connection.  Danny

I now have all 4 wheels off the ground and all wheels run free . Apply the brakes and all wheels lock OK. Release brakes nearside front Rock solid, offside  front just a bout turn it.  Rear brakes are binding but not as much as fronts. Bleed offside front and all wheels release OK. All there is in the system is single line master going to servo and out to union then off to the brakes. Danny

Today is the first chance to fault the braking system.  I Fitted 2 new brake hoses on the front. Bled the brakes and the front lock on again. I have not started the engine so the servo has not pressurised the system. It only locks the front rears are OK. Let out a small dribble from the caliper nipple and they release OK.  So is it the master or can it still be the servo.  Remember this is a single line arrangement and no pdwa valve. Danny

I removed the dual brakes 17 years ago and went for single system so the servo was on front and back. I never got a chance to look at them today but will keep you posted on how I get on. Don't suppose I can actually test if it's the hoses without replacing them.  

It was only the front that was locked. You have given me something else to think about now ☹️  

Thanks I give that a go tomorrow. Danny

Went out to get petrol for the run to Duxford tomorrow when my brakes locked on. (brake peddle rock hard) The only way of freeing them was to let a little brake fluid out of both frot calipers. As soon as I operated the brake  peddle they locked back on. So after freeing them again I drove home on the handbrake. I also noticed the heat generated has destroyed one of the front wheel bearings. The car is fitted with a remote servo, so I think It's either the servo or the master cylinder causing it.  Whats the best way of faulting it. Do I bypass the servo and try it, any suggestions welcome. Danny 

Vivid = Covid ...you think text prediction would know this word my now.

 

Why not fit an online fuel pressure regulator . I gave up on the new pumps a few years ago and went electric because of high pressure from new pumps. One new pump was intermittently putting out 9lb pressure. Danny

I can only go by mine.  When I renewed my hood and painted the frame some 17 years ago, I reattached the covers with normal rivets but I did place a washer between the head of the rivet and the plastic cover to stop the rivet tearing through the plastic.   Danny

This should help. Danny

They are pop riveted to the frame   Danny

You are correct Danny  

Email Chris he will sort you out. In the nicest possible way  😁

If you google it " Triumph paint colour 34 "   your get it online. I had no problem going to my local car paint shop and getting Triumph 32 (signal red) Danny

The bulkhead needs a good earth as all the electrics use the body for the earth. You need a good connection from -ve terminal to both engine and body.     Danny
