XF Rear Brakes Binding Problem
Hi,
I've recently finished an XF rear brake conversion on my beetle like many people to seem to have done on this forum. Everything almost went to plan,
except that the brakes are binding up on me (not locking, just dragging alot) when they get hot. Looking at the brakes it seems to have ample
"slide" clearance.
I rebuild the calipers thinking the accumulation of crud etc. was preventing them from retracting, and have assembled using copious amounts of PBR
rubber grease, however the problem still remains. It seems to me the piston isn't retracting any after being applied.
Has anyone had a similar experience? Any tips or things to look for?
Many thanks in advance,
Peter

Would the M/C (dual circuit from a '69 bug) have a pressure accumulator (?) in it for the rear drum circuit. I recall somewhere people going to a
kombi M/C on rear disk conversions. Would that be a possibility? If so, what model Kombi is the best and what is involved in retrofitting it?

The brakes on my XF don't drag, but I have had them jam on the sliding pins. Apparently I ended up only using 1 disc pad which wore through rather
quickly.
Have you adjusted the hand brake mechanism? You need to wind in the piston for clearence.

This is why guys are going EA , less parts to play with .
Pistion clearance
or more
look for * free play at your hydralic cylinder Peter , you need to > back the shaft out of the cylinder other wise the brakes come on > drag .

Have you replaced all the flexiable brake hoses.
these tend to brake down on the inside and not allow the pressure to release when the brake is up.
also check your brake cylinder push rod to ensure you have enough free play
