Just did my rear disc conversion, all on, all working.

Main problems

We bled on the the 2 rears with a 1 way valve kit, but the brakes are totally soft and spongy like anything do we need to bleed the fronts aswell?

The right pads constantly rub, not major on braking they make a funny ticking type noise.

Apart from that alls fine. Any solutions or anyone had this problem before.

 

You should bleed all 4 corners, furthest from the Master Cylinder first.

Now, depending on how the kit is installed, you might find that the bleed nipples are not at the tops of the calipers. They must be the highest point when bleeding as the air will get trapped otherwise, so you may have to unbolt the caliper and swing it up to bleed. If you do this and it is clear of the disc, put a block of wood or something between the caliper to stop the piston popping out.

Also, should be done with the wheels on the ground to open the load valves.

 

you have to bleed all four as above

remeber that the left front is connected to the right back so if you lose one of your lines you wil still have a front and a back braking ,otherwsie you would have either the front or back braking on its own - this could be fun!

 

Thanks people some good tips will give it a go on sunday, still a newb here but you gotta try.

 

Fair play for trying.... how did you get on ?

Pads rubbing may be just removing the high spots until they bed in.

 

what callipers etc did u use. was it 4x4 ones with 2wd cossie discs? also, have u removed your abs at all or kept it on there? just wondered as im just about to do a rear disc conversion.

 

Thanks for the advise on this post, cars running nice. As sump was off changed the oil to sikoline 15w 50 as recomended. Well worth the piece of mind. Conversion working well but do have to push the pedal down quite hard. But it was like this before the conversion was done.

Only problem is one of the right pads is rubbing, we did have a problem with the caplier hight and discs rubbing, but we solved it by rubbing it with sand paper and clearing the rust that was on it off.

Any solutions for the pad rubbing, as it will be nice when done.

We used a second hand kit mate, it was xr 4x4 calipers and the discs are cross drilled. As kit was second hand had to clean alot of rust off it, but was worth the saving. We also regreased all the bearings and used copper grease in the relevant areas.

As so noob, i need to judge our level of compitence.

If this was a haynes job, how many spanners would it be?

Just need to change timing belt, and fix the pad rubbing problem nut ill put some more miles on before trying to fix, as could be bedding in and at last i can go for a rolling road.

Many thanks too all that helped again.
