If it's like my mk1, they do just bolt on. You will need to put a bit of thought into the hoses and also the handbrake cable, neither of which are designed to fit a Polo. You will need a pressure reducing valve or you'll be locking up the rear every time you touch the pedal.

Alot of effort for very little gain..

no point tbh, just make sure your rear drums are adjusted up properly

looks much better though, i was told before i didnt need the valve as a few people have done this now might be totally wrong though,

Remember from reading another post about this, it is also less maintainence (sp?)

Easier maintenance. Who'd want to strip a drum apart, fucking about with springs and linkages etc to change shoes when you can just whip some pads out.

You don't really change brake shoes often though, and for all the messing about you would have to do get discs on the rear, you're better off just leaving drums on there. It's not really cheap to do either, i do believe you need different handbrake cables, brake flexis, master cylinder, brake bias. I've probably missed a couple things out aswell. If you've got plenty of money to waste then do it...

I hate drums enough to do a rear disk conversion...it'll help keep the backs up to speed with the bigger fronts...256mm and multi-piston FTW.

There is an impending thread in the post,which will be opened by me,on rear brakes. A complete conversion,from start to finish. I've yet to fit them myself,and more importantly (something I'm known for) yet to test them. But all will be revealed,hopefully within a couple of weeks - though I'm busy with work at the moment.

did anything come of this??

id be interested in doing this just because i like the look (and added confidense) of rear discs

Here here!! The drums are just not up to the job on the G40. If you wanna go track bound i have heard the drums are a complete waste of time!! I'm definately going discs at the back!!

I'll take the job of fitting discs over chaning drums any day

I did the disc conversion quicker......

IMO, I reckon it's worth it for the fact that you never have to look at a shoe-spring kit ever again. But as far as performance goes, not sure why you'd want any more power in the rear brakes on such a short, light car.

The main reason for wanting higher performing brakes on the rear of the G40's is when spanking it round a track you find that if you have high performance brakes on the front (four pots and bigger discs for eg) you start to boil the brake fluid giving large brake fade and pedal travel. Plus the drums under excessive heat tend to bind. Then again if you dont go tracking it then your ok really.........

drums are shat. i have to fit a new set of shoes every 3 events!

Yeah geezer,its simple really - Golf MK3 rear drums. Bigger (200mm). Straight swap. Slower wear and stronger braking. And still about as light as a disc,hub and caliper assembly (the drum/wheel bearing is 5kg,with just shoes and backplate in addition).

Discs are quite a pain,shoes take minutes to fit,its not Krypton Factor material - the twist and push pistons in rear calipers are no easier. Discs just look better.
