The standard repair of the calipers.
Suppose that the caliper safely removed from the car, is good).
A view of the brake caliper to which we aspire.
And yet have the appearance of average.
The piston has corrosional so squeeze can only be brake fluid, the duster has lost elasticity and broke.
The repair will not be deemed a repair if you leave the appearance as-is.
For a start it would be useful to go over the surface with a wire brush and a light hammer headed hammer, tap the layers "lump" of rust.
The next step I perform a wipe by electrolysis or hydrolysis as you wish in a solution of soda ash.
Cook caliper in the literal sense, when he's ready to get.
Remnants of rust in hard to reach places and zakaulkah become loose and relatively difficult to clean off with a wire brush, and then just a wire brush.
About this condition, the rust is removed by ~90%.
Next step sand blasting, thanks to the previous manipulation occurs significantly faster and easier.
Dilute the seriousness of this entry, funny pics, the sand penetrates even into sneakers, even in such quantities.
If you leave bare metal on the air it pretty quickly, just a couple of days starts to prokidyvaya new rust, therefore, not shelving them the caliper would have blown compressed air in addition to are degreased and covered with several layers of protective coating.
Brands of materials dictates the price tag
From left to right:
1.The acid or etching or reactive ground.
2.Acrylic primer.
3. Metallic paint ( as an option).
4. Varnish.
Well solvent it is clear why.
acid
the ground
metallic
in the lacquer.
All is well dry, and after it was assembled.
If parseek had not long replaced it with a new one, no polishing its chrome coating has not been raised.
For the speed, convenience and security for every transaction use your grease.
For installation of the piston Assembly paste, for napravami fingers special grease for them, for fittings and brake pipe copper paste.
Caliper ready to install in the car.
Well done.
Also began to prepare the caliper...
Only chose a slightly different method of cleaning from rye))www.drive2.ru/l/6576994/
current first half of the maximum should be about 100, then the bucket boil and clean almost to the minimum of 30 - 50, but it is all is written in stone, and 200 can deliver, but will come anyway as much as I can on this parameter is influenced by many factors, the thickness of the lead wires, good contact of these wires to the workpiece, the electrolyte density, the area of the electrodes, the degree of contamination or kartirovanija, after withdrawal me elektrodov and Sawicki to Shine digested current increased almost twice.

But on a normal lubricant and these are like...
By the way, what current are you boiling?
Tried svarochnik. Theme)
I have a basin 60 liters, 2 calipers at a time pulls.
However, after 30 amps meter begins to whistle)))
Sitting right now with the BP sculpt pokazatelyami for this case...
Wow;) Handsome ;) Caliper steeper than from the factory... now I know who on this question to go;) And by the way, the price can be found?
when kipjachenie oil comes down and the rust is converted that later is going to be good at painting, it's not like a sandblaster
shilo-rus
immediately attackstring not? without prelude
only you will last longer

Separately, piston not sold so that the article is interesting but useless if the caliper has worn only replacement of new and not a farm
Then the car is better to change... for a new one.
Never see, in our village there is no shit? Where the thread is over the hill there and in great numbers...

The piston are sold separately, as well as guides, as well. as bleeder...

+1
the piston without any problems for 800 rubles. At certain skill it is possible even with the pads to be changed.

Have the opportunity to photograph the condition of these calipers after all this time, without any further action on them if wipe the dust as the paint has not changed
Paint and soil with the heat, is not heat-resistant is necessary to paint the cycle parts ?!
Late afternoon, there is a place under the cylinder? ( my understanding is the cylinder that the whole caliper body in which is inserted a piston, probably wondering how he cleansed kanavki under the dust cover and seal ring, and
More nonsense I have not heard, I hope for your sanity, finish this conversation, I have a different opinion, it does not agree with yours, fix as you see fit
usually considered the max. wear 0.15 mm. Respectively, if you put a new piston into the cylinder, where the gap is larger than 0.15. It will be aplevich . I had these calipers. there is a cuff was not capleville as soon as the cuff was torn started smudges. Well, after 0.15 will flounder like shit in the hole.
And with good clearance even with paranoy the cuff will not leak.
What to measure? Again, I don't get it! Where is the development? If the piston without scoring it unfit for further use, it is not necessary to measure, except for self-interest, regarding admission if cylinder( caliper body), never, never ask such a thought even, now began to wonder what the tolerance is and where he had this information to find even, maybe throw a couple of links, don't want to delve further into this topic, what would be rusty and ugly 30 year old caliper I seperepere inner surface maximum was prekinuta light surface corrosion which flew from moment sandblasting, or brush after hydrolysis, do not remember exactly how many I have touched the calipers well pairs 30наверное, and even once the caliper was not defective due to an internal "production"
And then nedovolil even hear about it.
if the production of uniform without scratches, you have to measure. If the cylinder is in tolerance then change the piston and if the cylinder is out of tolerance, then there is no reason to buy a piston and sleeve cuffs. will flow.better to save the money to buy the caliper in new or good condition
Well, Troubleshooting is reduced to visual inspection if the piston is chrome tears or large fins on it to measure it is useless, however I see no reason to measure it if it's all right, he from that caliper to the other confused I can't, the inner diameter of caliper cylinder or as some call too nevizhu sense to measure, why? What'll become of him? Moreover, the diameter numbers cast on the case, and the diameter of the right piston in the caliper there for more than a couple of millimeters
it is not clear why there is no question of measuring the diameter of the piston and the cylinder.On the feasibility .
If there is rust then carefully go through sand, without fanaticism, and so in principle there is nothing wrong if the holes are not closed, if not cut in one place, then it is good to purge and rinse
I think you need to close all the holes before sandblasting? Especially the grooves of the seals of the piston, the hole fitting and other?
