when i mean adjust the drums up as much as you can is when i have ever checked cortina rear drums they have been way out of adjustment due to not being adjusted for 20 years which makes the back brakes activate slower and leaves a lot of braking force off the rears making the front work harder again at pulling up a car which is a weak spot all ready no point in making it do more work is there.
not adjusting them up so they are actully rubbing on the drum as thats just shear stupid.
btw drums arnt that bad and still more effective on 1st stop then a set of simerlar sized disc brakes its the stops after that kill them with heat.
rtfs if you read the statement i dont say that drums are better then disc's infact i show the drums weak point i also how ever show the disc weak point as well i am simply stateing that drums are not as bad as everyone makes them out to be hell ive riden in identcle cars one with disc rears and one with drums and the drums use to pull up better till about the 3rd stop.
and that is drum brakes are more effective in a 1 stop only application then disc brakes due to there wedging effect of there action being able to apply more force to a given area.
the reason drums are no longer used on larger heavyer faster cars is they can not disapate heat quick enough reducing there effiecency. which ironicly is the disc brake strong point as it can disapate heat much more quickly and effiencently then drum brakes but they can not apply the same force as drums for the simply fact they are rubbing not wedging.
for lamens terms spin a wheel on a car grab on the side to stop it how long does it take.(disc brake)
now spin the wheel again same speed and grab on tread pushing your hand into it with the same force the wheel will stop quicker. (drum brake)
and yes you do have to get them pretty damn hot same as discs but the discs will cool shit load quicker then drums ask kevin bartlet that.
cortina brakes are good enough to lock up in the wet. "locking up" as not a measure of efficient brakes
ok ill explain this then though you should know considering the dicks you have to deal with every day.
locking in the wet will happen with less effort then before due to increased stoping force. this becomes a problem with your average driver as when the wheels lock up and they dont slow down as quick as they like there natural rection is to press harder on the pedal which may even lock the rears (the reason why abs was invented) makeing an all ready out of control car even less incontrol.
so this becomes of concern to him as he may want to take an advance driver day etc so he can learn to modulate the pedal in the wet so as not to lock and go against his norm reaction with the better brake's.
and yes cortina brakes are crap but no less crap then cars of that era and if there are no major engine upgrade's or sprited driving on mountain roads then he wont need to add larger disc's calipers master cylinder's disc ass ends so long as he makes sure the system is kept in good condition.
btw yes i do prefer disc brakes over drums and am converting my car with larger front an disc rear due to more power coming along and i like to drive mountain roads with brakes not with out like i currently did.
