Binding Brakes

[les]

Yes good point there are usually two spring holes close together. The one that streaches the spring the most is the one to go for.

[kennatt]

if its all brakes that are binding,and everything else has been checked then surely it HAS to be the only thing common.the masterC. brake pedal or brake light switch allthough can't see how that could fail in any way.everything goes their own way after that point.

Some good ideas here and backing up what i thought; namely the master cylinder. I'm still not sure why a new Lockheed one would cause this problem.. It should be right shouldn't it? But we live in an imperfect world these days as regards parts quality.

I'm going to inspect the brake lines when i next get a chance as thats a good point; if one has got nipped up accidnetally that may do it. that could also explain why the fronts get hot whilst the rears get less hot, but then again, the fronts would get hot anyway as they are twin leading shoe etc.

i will also check the brake return springs but i've always put them where they were supposed to go so don't see why i should really change them. i suspect the fault is in the master and this may only be side=stepping the problem and not solving it.

Thanks everyone. I'll report back when i get a chance to look at it again.

It costs nothing to move the return springs - I did this when I felt I had 'oversensitive' front brakes and it did help that - needing a little more pedal force to work the brakes. I think it will solve the problem at no cost and little effort. If you feel the rears are then dragging - do the same - probably need to drill a new hole there.

Yes, ok, i may give that a go.

After reading all the articles surely someone must have a known good working master cylinder that can be loaned to him to try then at least it can either be ruled out or proved that it isthis item

It's a 10 minute job to re-hook return springs, and a very much longer job to swap a mastercylinder - and re-bleed the brakes..... I know what I would be doing.......

[dalgrae]

I fully accept that Roy, what I was trying to get at was for someone to offer a master cylinder to possibly try if all else fails .He seems quite rightly in my eyes to want to fully resolve the issue, if I had a spare cylinder I would certainly have done so ,then at least he had this offer to fall back on

[bmcecosse]

Indeed indeed - but I think it is a 'new' cylinder anyway, so presumably there is an 'old' one lurking.....

[Minornut59]

I have a few old ones but they are of unknown functionability... When get the car back into my garage i shall have a good look at the pipework and then consider swapping the cylinder with one of the ones i have. I think the old one from this car was leaking if i remember correctly so not sure what i did with that.

Repair kit?

Cheap enough though far from a guaranteed cure.

Maybe just dismantling and comparing, old and new will reveal what is going on? Hard to say till you try it.

[Minornut59]

Well, a repair kit would be good but in all honesty it shouldn't need it, being a new cylinder..
Hmm.

Anyway, have had a good look at the pipework, no issues there. All bends are gradual, and no kinks, dings etc.
I've been doing a few more local trips and doing lots of country lane driving which requires more use of the brake pedal and some days the car feels almost normal, and then when i drive it on other days you can feel binding.

I always park the car in the garage out of gear with the handbrake off and in the morning the car is easy to push back and forth, but after a run when the brakes are warm its hard to do so.

I'm just going to keep driving it and see if it settles down. I mean the worst that may happen is that the shoes will wear quicker.
i recall i had the same sort of thing on my Austin 1300 about 8 years ago after fitting a brand new master but that settled down after 6 months. This Morris may take longer as i don't use it daily anymore; its done its fair share of hard work!

Fingers crossed.

[bmcecosse]

It's not correct - at any time my Trav is free rolling with the handbrake off. Do try the return spring trick - you can always move them back again if you don't like it!

[Minornut59]

No, i know its not correct, which was the whole point of starting this discussion!
yes i will try the springs trick when i get a minute.
