rear brake pipe on disc conversion

[Anton]

That's a 3 door vitara caliper. Fairly sure I have a set sitting around somewhere waiting to be overhauled, but which will never go into my vehicle now.

So what angle did you fit them at?

[hamer]

they 270degree or 9pm lol
bleed nipple works out to be highest point

That sounds like the correct setup, although I had the same setup (Sammy front, Vit rear) before re-engineering the whole thing to use Rover 25 rear calipers on the back to get the proper brake balance.

Before switching, I had the same spongy brakes problem that you're having, and I suspected that the Vit calipers were somehow not bleeding right.

The Rover ones in, problems went away. Although the whole system was bled dry, re-primed and re-bled so it may have been nothing to do with the Vit calipers at all!

so just keep bleeding fluid throu?
if that dont work il strip the calibers :(
thanks mate

When I did my rear disc conversion earlier this year, I had to bleed the brakes though at least 4 times before I got a decent pedal. Now they work great. I think it just takes a while to get all the air out.

Ferris - perhaps it's a case of needing to let everything settle, letting the air bubbles collect, and then purging them?

I have a feeling that because I started fresh, with a completely empty system and brand new dot4, air pockets couldn't form - I also massively "over bled" mine (used 2 full cans of dot4) when the Rover calipers went on.

I may get more dot4 and re-bleed, just for safetys sake - you never can be too sure of your brakes, eh?

Turns brake bleeding from a long-winded dirty 2 man job (up, down, up, down, up, down, etc) into a one man 5 minute job

(You can get them for about £12 if you shop around)
