Thread: 35 inch tyres.

just ebay'd defender calipers $183-00 buy now single not pair and new not second hand

then you would need pads as well - bloody cheap given the spacer for my disco calpiers were $500-00 to buy then labour on top

Sounds like a plan to me now to get a job so I can pay for them

So my alternator must have been changed from small pulley to big pulley then at some stage? I definitely have the larger belt on 1595mm.

That brake upgrade sounds very interesting too, will have to look into that. I couldn't even lock up the 33's on road if I tried with new rotors and pads.

Remember 1.22:1 high range also

A thought does anyone know if the defender brake booster is larger than the disco one? it would make sense as the calipers are larger, if this is so when fitting the defender calipers would it be worth fitting the defender booster as well?

I have 275/70/16's on mine and I must admit I nearly have to put my foot through the floor to do it and have my bum off the seat pushing so hard but I can get my disco to lightly skid on the black but it is a hell of an effort

What about the master cylinder too

yeah I should have said the whole assembly, logic would say that if more volume is being used in the piston then a larger booster and master cylinder would be required

ok so since my discs are only 10k old (once they need replacing replace with ventilated) then all i have to do is find 4 defer cailpers a booster and a master cylinder then my dozer will stop and i wont have to use the car in front to stop me from going through a red light. Sweet now all i have to do is save like a mad man again.
Thanks Blitz

Wouldnt Change booster and master, also wouldn't worry to much about vented rotors unless your towing, good idea if doing the lot at once, but not seeing as you've just replaced them
