Maybe it needs new calipers
I think there is a differential on the brake line, between the two calipers, maybe it needs some inside cleaning. Or it may be an easier fix, you could have air in the 45% caliper and if you do proper bleeding of air, they'll both work fine. Or, it could be as you've said, the case of need of new caliper.

Re: Lefty’s B - Progress Topic

We had a LongLife Stainless custom made fitted in 2011 on our 2005 "B".

The normal OEM system had three boxes. Middle, Middle-Rear (before axle) and Rear/Back box.

Even if you have a non standard stainless system any quality stainless custom system fitter/company, such a LongLife (franchised around the UK) will be able to repair or remake/fit as required.

Re: Lefty’s B - Progress Topic

I have a Longlife exhaust too. Mine was fitted a long while back. 2010 or before maybe. I highly recommend.

Re: Lefty’s B - Progress Topic

Thanks for the thoughts guys, I will have a look at the weekend

Out of curiosity, do you have any idea of what it would cost for a full Longlife exhaust system?

Re: Lefty’s B - Progress Topic

Back in 2011 our Longlife system cost £300 fully fitted.

This was CAT Back and consisted of a middle and rear box and tail pipe.

Basically they will make up what you want using choice of boxes and end tail pipes with all tubing cut and bent as required including custom hangers. All in stainless and TIG welding.

I can lookup up what item part numbers were used but these have probably changed since 2011.
Thanks LeftyGreg thanked for this post

Re: Lefty’s B - Progress Topic

Sorry to hear about your MOT failure.
I thought the brake compensators were to balance between front and rear but I'm still learning my way around. That still might be a problem though. You've probably already found this thread which may help:

Thanks for that, I am sure the price has gone up since then, I was worried it was going to be really silly money, but at least that gives me an idea and once I inspect it at the weekend, I can make a decision based on how bad it is. If I am lucky, it is a section joint and taking it apart, putting some sealer in it and putting it back together may be the solution.

Helpful information, thanks, I have ordered new calipers and when I fit them, I will have a look at it

I thought Stainless Steel exhaust were supposed to last forever

Can this be repaired with exhaust repair stuff, or will that not stick to S/S

Looks like it has been done before and some stuff came off it when I was cleaning it

Re: Lefty’s B - Progress Topic

Good marine grade Stainless will never rot and last forever. However stainless is a brittle material so for exhaust plating/box walls needs to thicker than normal mild steel.

That crack you have can not be fixed by any compound. It needs welding and preferably plating over the weld to build up the support strength between the pipe weld joint and the box outer rim/wall.

Also what is odd about what you have is the the stainless box has been directly welded onto the mild steel pipe. Normally the box would have it own stainless steel inlet tube that would sleeve fit over the mild steel pipe. Also this stainless inlet tube would form part of the internal construction and support of the whole exhaust box.

All this probably explains why yours has fractured.

I thought that was strange too. I believe that this exhaust came from DTR, so again I am surprised that it isn’t full stainless steel.

Would gum gunk get it sealed enough to get through the MoT?

What I want to do is get it through the MoT and then be able to take the car somewhere to get this repaired or replaced

At the moment, it is all about temporary repairs

Re: Lefty’s B - Progress Topic

Yes probably enough for the MOT. You could also cover with aluminium/other heat resistant exhaust tape which might prove more flexible.

I've never really understood the exhaust leaks rules post CAT unless there is a structural/fire risk reason. Technically, as do many older cars you can have a straight pipe from front to back or bent out to side etc. So a small blow on a joint, protected by a heat shield is far less worse IMHO. Can't see the CO poisening aspect either unless you have holes in the floor pan as well.

Re: Lefty’s B - Progress Topic

I have ordered some gun gum and one of these

Total cost £10, so not much to lose if it doesn’t work

I will also look into a total S/S system as, like you said, this seems to be some kind of cheap hybrid

Re: Lefty’s B - Progress Topic

It may or not be of interest but I just spotted one of PaulieCabs latest videos where he has a similar inspection failure on his brakes:
https://www.youtube.com/watch?v=zgSFnWNUIPg
I just got jealous of how little surface rust he had to deal with down there.
Thanks LeftyGreg thanked for this post

Thanks Chris, had a quick look at the video, will watch it properly later.

Had 2 new brake calipers delivered today and got the exhaust welded on Tuesday, so some work to do this weekend

Will have a look at the compensator valve while I am under there.

Does anybody know if the valve is on both sides, or just the one?
