Brake shoe fitting help

[Paullou126]

Hi not long had my 126 bis h reg I’ve just got a set of front brake shoes to fit to the front to finish of it’s recomission.
Will I need new adjusters if so where can I get them from thanks

The adjusters are part of the shoes themselves.

Hi thanks I see now I was looking at the anchor pins and springs it’s been a long week thanks

hi, while going to the technical inspection, the rear breakes which I replaced myself turned to be out of tolerance on braking test, everybody has told me I need to adjust the shoes but as you say, the adjusters are part of the shoe itself, then how can I solve the problem?

I only thought I need to take the break covers ( idk the english word) to polish it?

Your adjusters may have sized up Tom. If you remove the drum and lever the shoe in it should move on its adjuster without too much pressure. If they move ok try seeing if the wheel cylinder moves in and out on both ends by pushing them in they could be sized up to.

To adjust the brakes, go into reverse and speed up a bit- then suddenly slam the brakes.

I replaced the whole break set. cylinders, shoes, springs... everything

whats the difference from doing it forwards?

[Xylaquin]

presumably since the car is being driven forward anyway, and the brakes are being used, they're already adjusted for that direction.

That explanation is probably nonsense, but honestly the reverse/slam process isn't!

[tomviam]

and anything else for explaining why after replacing the whole break kit, the compensation was out of the tolerance? In Spain, the tolerance to pass the technical inspection must be lower than 30% respect the other side break.

Have you got the correct size wheel cylinders fitted? Rear ones look almost identical to the front ones but have a slightly wider body (thus increasing the brake efficiency) I fitted the wrong one once on one side and curiously is was about 25% out compared to the other side.

hmmm as far as I recall, yes both where the same...I will take another look, but let's assume both are the same, what can cause it? because the mechanism is very simple

[Gadge]

Well really it could only be either the shoes sticking on their adjusters which to be fair does happen or the wheel cylinder is seizing up. Those are the most joy two parts that move really.

There is another possible cause which could be the pipe or hose supplying the brake fluid to the cylinder. A kink in the line perhaps?
