badgerspitfire Posted August 15, 2020 Author Report Share Posted August 15, 2020 Yep, mine are Type 14s. Neither calliper had any markings or labels to identify them. I've sent my old callipers via the TSSC Shop to get them refurbed. I thought about trying to sort them but didn't want to take any risks when it comes to braking systems. I'd hate to have an incident one day for the sake of a calliper refurb. If the refurbed callipers fix the problem I'll see if I can send the 'new' ones back, or at least put a note on the forum letting people know about a potential problem with 'new' type 14s.

Chris A Posted August 22, 2020 Report Share Posted August 22, 2020 Hi all, I've been watching this thread as I have the same symptoms. There is an article in the Oct. 2019 Courier mag, p.16, on this subject and I had been thinking of following it - the advice it to remove the pads and put something a little thinner in place and pump the brakes, well that is a sort of summary. I have been away for 3 weeks and left the brake pedal wedged on to see if this had any effect, i.e. the seals giving a little. Well I have been out in the car and it seems better, not perfect but less travel. I want to get the rear brakes adjusted to see if this also reduces the travel.

mark powell Posted August 22, 2020 Report Share Posted August 22, 2020 I had similar problems with my type 14's on my pick-up conversion. Wedged the pedal down for 24 hours and travel is now acceptable and MOT pass (twice) Link to comment Share on other sites More sharing options...
badgerspitfire Posted September 12, 2020 Author Report Share Posted September 12, 2020 My old (now reconditioned) calipers came back this week, so had chance to fit them today. It has solved the long pedal travel. So, it would appear that the NEW BUILD TYPE 14 CALIPERS are potentially rubbish/not good. Worth noting if you are planning on changing calipers...

Colin Lindsay Posted May 11, 2021 Report Share Posted May 11, 2021 Just despatched a Spitfire off home with its' owner after a complete brake rebuild and the pedal pressure is woeful. I was so worried about it I took it back inside this morning and rebuilt the rear brakes again then rebled the system. New type 14 calipers, discs and pads, new stainless front hoses, some of the pipes remade, and new master cylinder. I couldn't believe how poor the pedal feel is. The rears are adjusted as tight as free movement will allow. I'm hoping that as the front pads bed in the feel will improve, as Pete says on page 1. The old calipers were seized on one side but I may yet rebuild them, just in case it is the fault of the new calipers and doesn't go away in a short time.

johny Posted May 11, 2021 Report Share Posted May 11, 2021 need to look at the pads after a few miles Colin as Ive got a caliper that, for some reason, takes a while to bed its pads in completely and until then the pedal action isnt so good...

Mathew Posted May 11, 2021 Report Share Posted May 11, 2021 Are the hoses old? Could they be expanding? What bore is the master cylinder. Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 11, 2021 Report Share Posted May 11, 2021 do also check there is some free play on the M cyl pedal push rod , a seized pedal pivot holding the pedal from returning stops the cyl recuperating Pete Link to comment Share on other sites More sharing options...
Colin Lindsay Posted May 11, 2021 Report Share Posted May 11, 2021 All rebuilt with new master cylinder 5/8 bore as the one that came off but with the large plastic reservoir. Stainless hoses fitted to front. I'm hoping it will just need a few miles to bed it then I'll recheck. Link to comment Share on other sites More sharing options...
