Quick trick on removing siezed in pipe unions…

Critical tolerance machined mating surfaces, assembled and pressure tested
within clean environment. Living on a vehicle for years in the extremes of
temperatures. I’m guessing that splitting them may result in distortion,
non-flush surfaces with high risk of contamination and likely pressure
testing would be beyond the means of a home mechanic apart from sucking and
seeing while fitted on the vehicle – could fail at any point in use at
worst possible moment.
Arm chair mechanics….don’t you just love ’em? Brakes and the subjects
related will be coming next year. Have you seen Action Manuals on You Tube?
He has a short vido about the seals. From here I can see the vid on the
near side of this video player.
the world desperately needs you to do a Landrover Caliper piston overhaul
vid that doesn’t have some muppet… a) splitting the caliper in half. b)
pointlessly heating caliper on a stove while putting the pistons in a
freezer thinking that those stupidly low temp changes would allow
expansion/contraction to any notable benefit – when said pistons and seals
would have fitted anyway.
that said I’m about to fit new !hitpart calipers to my truck while I have
the factory calipers on the bench to fit original seal kit. Thinking of
stainless pistons but not sure.
You are right about the units distorting after years of heat, constantly
heating up and cooling down quickly. . Pistons usually last a fair while if
they are chrome plated, saying that I guess it comes down to quality of
parts supplied. What would the benefits be from fitting stainless pistons
other than corrosion resistance?
Arm Chair mechanics, Don’t you just love ’em? Brake stuff will be coming up
next year. Got a lot of stuff to do. Just looked at Action Manuals,…he
splits the caliper…
sorry replied twice in a different way dur…..
I brought new calipers for my Disco for the rear axle as the originals were
really shot. Would have been a quick job however the ’95 disco had metric
fittings for the pipe and I was sold the older RR type with imperial
fittings. Just made the job last longer. They came in blue boxes. After 3
years the vehicle still goes through MOTs without brake problems. Not that
I own the Disco anymore though!
aye was just watching his vid from your previous comment and seen he split
the caliper. I have not overhauled the seals/pistons on a LR caliper (yet)
so might be wrong but on vehicles I have done (80’s fords and vauxhalls) I
was taught not to split the caliper. Spell check wants me to use the word
Calliper.
