Title: Golf Mk2 to Mk4 rear caliper conversion
Post by: mk2rolf16v on 06 December 2010, 21:02
hi,
ive a 1990 mk2 16valve, if i were to replace the rear calipers for mk4 ones, what version handbrake cable should i be using? ive been told by some i need pre 88 cables while others say to use existing, what are the differences between the two, and which one should i be using?
any help would be greatly appreciated.

thanks

There is no point at all mate, the front does all the work. Unless you just wanna do handbrake turns

i had 90 spec gti and used the standard cables fine, my rears/handbrake was sh!t. worth while if your keeping it, in my humble opinion of course.

All Mk2 Owners will have to look at doing some sort of conversion in the coming years as VW has discontinued the Rear Calipers...

You can buy the carriers (Fecking Dear Thoo) but not the calipers as I found out a few months ago when I wanted new ones....

You can use the existing cables and carriers on a 90' spec Golf, but the Mk4 caliper uses a 'banjo' type fitting for the brake pipe.  I got my conversion pipes from C&R Enterprises which are made by Goodridge, and they were only £20 or so.

There is no point at all mate, the front does all the work. Unless you just wanna do handbrake turns

Thats right, there is no point in swapping out a crap set of calipers for a good set. And after all you don't need rear brakes for an MOT.  :rolleyes:

@tech1889/Lewy : thankyou for the info, you're right, my mk2 calipers are starting to stick, and notice at times when slowly rolling to a stop - theres a slight noise.... ive got new discs and pads on less than a year old and one of the discs i noticed scoring marks probably because the calipers not releasing freely. at the time when discs/pads got changed, when winding the pistons back, was a lot of resistance, and had to use spanner end for extra leverage, surely rear calipers are on their way out??
and finally, you're right Lewy - mot is in january, gota get it fixed asap, my car is my pride and joy so why should i be interested in doing handbrake turns (as some member suggested) - jus wana pass the mot.

doesnt matter what year mk2 you have, you always keep the std cables. pre-88 mk2s used different shape calipers which means you have to mount MK3/4 calipers upside down, or modify the cable routing. you can swap to later spec cables as they'll be way too short, the difference is down to the style of the handbrake lever not so much the way the calipers are mounted to the beam.

as above need conversion hoses to fit MK4 units, later mk3 units have the same design of handbrake mech so dont sieze as much as mk2, but are a direct swap onto your car. basically look for a handbrake spring, if it has one its a mk2 caliper, if not its later mk3

A little of this http://www.golfgtiforum.co.uk/index.php?topic=49436.msg979860#msg979860

Then after, some of this http://www.golfgtiforum.co.uk/index.php?topic=49436.msg1000233#msg1000233

do not use a g-clamp in place of a proper piston winding tool!

Not only an MOT fail but trying to control a dodgy revving mk2 in uphill traffic can be a handful.
Holding the revs high enough to not stall and reach for the foot brake. Sod that!

Ive converted to the mk4 setup. You just need the banjo brake lines.


Working handbrakes = win

is it normal practice to loctite the carrier bolts?

I've never used loctite on a car, just torqued to the correct figure.

Ive started to use loctite on bolts and screws.

We build road side equipment at work. bolts work loose with vibrations if no loctite is used.
