Rebild front calipers FIAT Bravo with his hands. Part 1.
Hello!
This record is exceptionally visual-informative for many. As such things you can easily do on their own in the garage and not to carry large amounts of money to one HUNDRED. Yes, he will always do better than what someone else is, the more we all know how the station is treated to the quality of the repair.
Today TyrapuH decided to dismantle the front brakes on his FIATе, fully atypicality front calipers, brackets, hoses. Pads and rotors respectively. The whole thing naturally produced in the garage. The caliper bracket itself clean elektrolitom from rust 20 years. Neither a brush, converters, and other hat You do not remove the crust of rust. Only sandblasting or electrolysis is our favorite.
First remove the caliper, the problems with the bolts not there, so the caliper bracket was removed quickly. First removed the left caliper... But the piston in the cylinder and hands it not to pull. No the rods are not bought. What to do? And all easy-to-fasten back brake hose, start the engine and slowly press the brake. The piston goes all the way to the end. Then it bring down to swinging a hammer. And with the second stepped support what I realized only then) the System with the air, and the hose from the left is hanging himself, not pedal to squeeze. With a hammer and chisel and other things, too, the piston doesn't pull out! What do we do? Do not panic.
The yield was found quickly, the benefit of brains. Take a vise, Unscrew as much as possible. Hold the piston over the edge who was freed from under the anthers. And the blows of the hammer on the caliper throws it. The piston remains in the jaws! Watch the video and you will understand everything:
Themselves rusty pistons, cylinders, without producing. That is to lick caliper, new pistons and dust caps and is new Lagsters.
Next, take a bucket of water, fill soda. The bed of the sacrificial metal, neatly caliper (the Main thing that is not short circuited), a victim of the + on the caliper -. And turn on the current source to the network. Leave this matter for approximately 20 hours. The liquid immediately began to seethe, that is, the heat is gone in the course=)) So be it!
After an hour take out the caliper (First turn off), must be black. Remove brush, drill all of the trail where you can. It will look like this:
Then again throw the caliper in a bucket and cook for 20 minutes. Once we get see that the metal is already white with foam, clean actually. And then the whole thing brought a drill with a metal brush to finish the Shine. A drill by the way is very convenient! A whine that not everywhere podlezet. Guys almost everywhere podlezet!
After all movements have the ideal position:
By the way fitting prokachannye after the first treatment, he got out okay.
Further, according to the above scheme, clean staples! They were also podsahania:
After all the machinations we have here such beauty:
But this eventually became the sacrificial metal:
I think it turned out above any praises really! Will continue at home caliper to assemble, paint, gruntuetsya and put on the car.
This turned out to be a record. I think many will benefit from reading it.
Why carry the loot in STO, when much can be done by their own hands and on the conscience!
Thank you all for your attention, until we meet again)

Thank you. Nothing suffers. We are nothing is not closed. Current regular charging for the battery. 12V probably. On the bucket approximately 4 palms of soda.
And again, then boil in plain water? Pineapples don't need to add?

Thanks for the article — very informative. But I would like to read more about electrolysis if you can: how much water, how much soda, the voltage and current source that the sacrificial metal does not suffer if the master cylinder after the procedure and whether it is necessary to somehow protect or plugging something?
took out the piston on the car, just removed the slide and push on the brake until the piston will not come out so well fought podlinnym slide, the pressure makes his own, only had the car run without the vacuum collector did not want to get))
the pistons can be pushed by compressed air, but blowing gently on a few, ATO missions, can a trauma to. be sure to put fanerku that shot her.
for pulling the pistons found an easier way I air compressor squeezed in a second flew and slide longer boiled in caustic soda output less rgy
I'll wait for the report...be sure to think yourself to do the same operation)
mate, I'm then going to get bombarded with questions, want to take the caliper I yapii from the Mazda RX8,but there is not much rust:)))
It can be in the collection if the reaction to threads get, you should raskrutitsya. For any try, sure.
I probably already fed up, but one more question: item need to completely disassemble or Assembly to throw if something does not Unscrew (I just now got the suspension sorted itself, and something that well in any does not want to Unscrew: so I think, to demolish everything completely in any way or is allowed to throw in the collection)?
Yes, calipers are the same. The usual charger, 12 V. Well, if more powerful, it is only +
Yes, I have no doubt that the photo is the same item, just the result is excellent! The charger for the batteries, probably any good?
I assure you that all the photos in reality made. All on their own in the garage. Thank you.
))) The brush in a power drill which. Okay nozzle) this is the perfect caliper and take a chisel, for example, bale-bale, rip off the perfect layers and all will see) Just sandblasting and the more powerful the better. But for sportov it does not matter, the disk is such that the drum its the rust)) the Main band of the cylinder above the cuff carefully cleaned and lubricated the right to put (Slipkote 220R, for example). Who is at the level of the calipers is engaged — there is sandblasting. But for parts of the body with this level of rye, where the metal is thicker and not through another — is sandblasting.
The ideal caliper would be only after sandblasting. Brush this rust zapolirovan.
