dont use powerhouse

[martin]

just stripped some calipers apart for a forum member. as he is,nt too happy with the finish on the ones he had rebuilt by powerhouse[they advertise on ebay]
what a bunch of tossers. had to struggle like mad to remove the pistons.
and as you all know, when rebuilt,pistons should move freely.

, look at the pistons, a lot of the marks are fresh,so make your own mind up. [you can even see the marks on the pistons where they have rubbed them with wet and dry,so would of known how bad they were]but why rebuild calipers with pistons that bad.
if you read this powerhouse, sorry that I am knocking your work. but really, come on, is this your standard.

their paint is shit too

Glad there not mine,
Not a good advert for there work, was there any red grease on them?

[martin]

yep, loads paul.
but when I rebuild calipers, I never use red rubber grease,
the only thing inside a hydraulic system is fluid, so why use loads of grease,
if the pistons were that bad, why did,nt the company phone the customer up advising that new pistons were needed,

I know the customer has rung them up and guess what, they don't want to know.

I will be replacing them with nice new stainless steel ones


all sorted now.

ooh look at my lovely brakes

[fred]

what would a so say pro firm charge for such (the pitted uns)

what would a so say pro firm charge for such (the pitted uns)

About the price of half a sheet of wet ,dry.

shonky mf's

[daz680]

Can't remember the exact cost, think it was about £165 with postage. Used them because I thought I'd be having a professional job done. Oh well all sorted now thanks to martin.

[nikfubar]

£165.00 ouch thats criminal for the way they sent them back to you, looks like all they did was change the seals & give them a quick squirt of gold paint.

Just literally finished rebuilding mine today (hopefully to a good a standard as Martins) & I know it's not cheap mine cost £250.00 in parts & powder coat without replacing pistons as mine had no rust or pitting.

[Professor]

You should use rubber grease to prevent corrosion in the brake caliper seal grooves etc, it will also lubricate the seals including dust seals. Brake fluid attracts moisture and hence encourages corrosion.

Red rubber grease is veg based and designed for use with brake systems, you can also buy brake seal grease by nissin.

Is that powder coating on fresh calipers Martin? Looks very nice

[martin]

it is, i hae some nice 2 pack ones at the moment.
i hear what you are saying about red rubber grease.
its ok to put a very small smear in the grooves, but go carefull not to put too much in.

[headcoats]

I whack red rubber grease all over the grooves and smear the seals too and just wipe the excess off.
If there is any inside the body it will come out when you prime/bleed the brakes.


Powerhouse must be hoping nobody strips the calipers when they get them back Total disgrace

[Virgie]

It is amazing what some companies think they can get away with - that workmanship is a disgrace. Does anyone know if it's possible to get new insulators as mine are starting to look like the ones that Powerhouse have mangled. On checking a spare set of calipers I have the insulators were also starting to degrade and will probably fall apart if I force them out. It's a strange fibrous material they are made of, so maybe 22 years down the line they are all degrading and falling apart? I assume that it is important to keep them to help with heat reduction between brake piston and brake pad?

[martin]

if it were me. i would,nt worry about the insulators. dont really know of many bikes that use them.
wemoto sell seals and pistons. or there is a guy on ebay that makes stainless steel pistons,

i have one set [8 pistons] left that i would sell for £100 if anyone is interested

[500bernie]

£34.97 from Cradley for a piston and insulator
