Replacing Rear brake disc

[tommyardin]

i only mentioned wd40 (the devils semen) because unfortunately that seems to be the only lubrication some people tend to know about
wd40 your ignition barrel  - NO NO NO (use carb cleaner then a graphite spray - never an oil) (try carb/brake cleaner first as a test next time)
wd40 your tight bolts - NO use a proper penetration spray
wd40 your wifes arse - NO NO NO be nice and use Another type of penetration lube


wd40 is great for some jobs dfont get me wrong and i always have some but it is rarely the correct thing to use
we have a can in our rally cars tool box but rarely use it back at the garage is its primary roll is water displacement
can it penetrate YES - is it the best HELL NO

Yes yes yes for that job I find that little red straw is just perfect.
