Thread: Bleeding Brakes!!!

I notice one problem that hasn't been mentioned here, but has cropped up before for me. A while ago a friend had a shortie that he could never get good brakes on. It turned out he had referenced a long wheelbase rear wheel diagram when setting up the shoes and springs. They run the springs between the two shoes, but they have two snail cams on each wheel. Shorties only have one snail cam and the spring goes between the leading shoe and the peg on the backing plate. The result was his brakes were awful despite having no air in the system and the adjustment was locked right up. This may not apply in your situation, but it may be useful to someone.

I can't think of anything else obvious that may be doing it. The idea of raising the front of the Landy (mentioned earlier) was for early vehicles when bleeding air out of a CB master cylinder. Good luck.

Hi all thanks for everyone's help, made the vacuum bleeder today made no difference at all.

I don't think there is air in the system, but a problem at the shoes and drums,but what?

The springs are hooked up post on the shoe to post on the backing plate, what else is there to them.

Maybe something like AdsLandies had going on?

I'm just about of ideas no I AM out of ideas I'm about ready to drop a match on it all!! seriously

Maybe post a more specific location than just your state, and have someone with a few decades Landy experience have a look at it with you. It is sometimes necessary to get a fresh pair of eyes to locate the problem.

If you clamp all 3 hoses, the pedal should be rock hard and right up at the top. Is that the case???

If the pedal goes down more than 1/4" in the above case, you need to adjust the actuator rod.

If the above is all ok, try clamping each wheel cylinder with a g-clamp. While clamping the hoses to any other wheel cylinders. This will make the cylinders minimum volume - making it easy to get any air out. If the brakes are still rock hard when the wheel cylinders are clamped, then it can only be adjustment.

You should also be able to tell when you bleed each side if a clear stream of fluid is coming out of if it spurts out (still has air in it)???

Thanks. I have a few decades of landy experience.

I have done all of the above. read the thread

Read in the haynes manual at the end of the braking section in fault finding it says:

Symptom: Pedal feels springy

Reasons: Brake linings not bedded into the drums after fitting new ones.

Anyone had this with new shoes? And would they be that bad?

Sorry I tried to help.

FYI I did read the thread before posting. I cannot see where you state how much free play you have with all 3 clamped? There should be no noticeable "hose flex" that you refer to.

You say you have bled 15L of fluid, but not if you are still getting bubbles?

I cannot see where you state you have clamped the cylinders (rather than the hoses)?

If you have "3 decades of LR experience" you should know how to adjust linings by now. I have never had problems with "lining flex". I have however had plenty of adjustment issues over the years.

If there is no air in the system, you should be able to pump the pedal a couple of times and get a hard pedal. Can you? If so, you should be able to hold your foot on the pedal and it will not go down.
