Thread: Little advice regarding Brakes

Ok, I don't know much about the series Landies, but I'm guessing the spring you snapped was a drum brake shoe return spring.

If your master cylinder was working before this failure I don't see why it would have a problem now.

First question, have you adjusted the shoes out for minimum clearance on the drums? if you have a lot of clearance, all the stroke of the master cylinder might be taken up over coming that. Can you get resistance on the pedal if you pump it quickly?

If so, does it stay pressurised or does it slowly sink to the floor?

unless the M/C went dry at some point, I've seen this damage the cups

I kept the Master Cylinder topped up, after I noticed the pedal getting soft.

I've adjusted the shoes so that they are touching the drums.

too late, you sucked in more air... bleed again as you did to start with. Atleast you know you'll have given it a good flush

If you got any air in there you will have an air lock in the cros pipes on both the front left and the rears.

if you dont have a good vacume bleeder the next best way of flushing it out is with a set of hose grips (they compress the hose so it wont let fluid flow without damaging the hoses) then with all 3 hoses blocked pump like mad till you get a firm pedal with the pedal up as high as you can get it. Keep downwards pressure on the pedal and then have someone open a bleed nipple and then release the clamp. when the pedal hits bottom do it again.

after a couple of goes at that its time to try it without the hose grip on one hose... repeat as needed till youve gotten a good pedal without the clamps on all hoses.

For a one man operation I would recommend to back bleed the system , starting with the rear pax side ,then the rear drivers side, front pax ,driver side front.Dont have a back bleeder no problem, get an oil can old type get'em up here for a e10 .use some soft 6mm silicone hose or in your case the hose off the bleeder you have.clean the bleed screws and refit them .Then empty the master cylinder using top of oil can and discard fluid.now fill the oil can attach the hose to the bleed screw open same and pump until all the air has reached the resevoir . repeat as necessary on each wheel and keeping a close eye on the master cylinder.WEAR SAFETY GLASSES fluid makes eyes very very very sore

This is a good way of doing it. Make sure that everything is as clean as possible and if there is any suspicion that anything is even slightly oily, wash it thoroughly with metho.

Another suggestion that can help is to back off the adjusters, remove the drums, and clamp all the shoes together so as to minimise the space inside the wheel cylinders.

One of the advantages of reverse bleeding is that you can push through a lot more fluid than from the M/C without relaxing the pressure (even if you have to stop to refill the "oil can", and shut the bleeder off while you do it, gravity is on your side - the air bubbles will not tend to reverse movement like they do when you take another pump on the pedal).

Dave's suggestion is also excellent - block off all except one part of the system, and bleed that; when it has no air in it, go on to the next part.

you want a hand with this on the weekend......?


i should be able to come around either on saturday or sunday.......not sure yet.......


and if you have a compressor....i can bring my brake bleeder with me and suck all the air out........



it shouldnt be too hard to bleed.........as long as nothing is damaged......






if you need a hand just let me know........
