rear brake cylinders
« on: May 20, 2015, 07:00:02 PM »
Fitting new rear wheel cylinders at the moment and noticed that the locating pin on the new wheel cylinders is only suited to the drivers side, do I simply remove the pin and rely on bleed nipple to locate it or do I drill a hole through the backing plate where it should sit?
Cheers,
Steve

As fare as I know the cylinders fit both sides but dose not mean that I am right. As my rear backing plate was also wrong so just drilled a hole in the plate. Don't just really on the bleed nipple to hold it in place as you might won't to stop.

Enlarge the hole.

Annoying but no choice apparently with the Quality (?) product supplied today.

If your painting the backing plates, get a good fit of the Cyl including bleed nipples.

Mount it all up, ensure you are happy with the fit, then paint,  ::) from experience  ;D

The location of the pin is to prevent you from fitting the wrong size wheel cylinder. There are several different sizes and each has the pin located in a different position. The brake back plate is only drilled for one size of cylinder, and the holes in a pair of backplates aren't the mirror of each other i.e one will have its hole towards the front and the other towards the back, because the wheel cylinders aren't handed. If you find that the hole is in the wrong position on one side it means you don't have a pair of back plates.

Make sure you have the correct wheel cylinders for your application and that they are both the same diameter.

Cool.

My back plates have a couple of holes, when I converted to front disks I had to drill new holes for the smaller wheel cylinders at the back.

I've noticed this too, as I am putting 5/8 cylinders on due to new front discs. Can I just remove the locator? I noticed that my old cylinders dodnt have them either.

Hi,

you can remove the locator but you are better off drilling an new hole in the backing plate to match the new position of the locator.

Without the locator the the cylinder gets moved around and over time it will oval the large hole around where the pipe fits and this can effect the brake efficiency and pedal and eventually you have to replace the backing plate.
