Dunlop brakes

[Boris64]

All my calipers gone to be restored



They’ll be sand blasted, plated, and sleeved with
Inox sleeve
My question is about this système :

All the pins are very difficult to introduice in the piston hole,


So, is it inerresting and secure to cut the pin or drill the hole to stop the systeme ?

I understand some people have removed the pins with success. However, as the article you posted describes, they are part of the adjusting system to maintain proper pad to caliper clearance. IMO opinion, they should be kept so everything operates as designed.

I have to confess I replaced the brake calipers and pistons on my 4.2 as the new cylinders have a modern day seal which pulls the pad out of contact with the disc when the brake is not applied. One of the problem with the original cylinders as I understand it , is they retract the pad too far back and hence when you apply the brake pedal the travel is longer than ideal. The cost of the new piston assemblies fixed to the original calliper is probably much the same as refurbishing the originals. I am all for originality but in some areas technological improvements have been developed over the last 60 years or so. I also opted for the vented front disc and 4 pot calipers. I have a car which really does brake like a modern which is reassuring with so many cars on the road and such poor driving standard today.

FWIW, I have not had issues with the original set up.
