Wow! That comment was very nice to read first thing in the morning, after i woke up! My rest of the day will be now much better. Thank You!

The best video I have seen on brake jobs, not many mechanics clean parts as you did. You seem to be nice chap.

What can happen if protrusion does not fit into the hole on the brake piston?

Excellent.

I'm at 2:40 and I'm already going to say, great view my friend!

great video with the writing info also . my vibration thing is rusted out on my GTC so can't turn it like your one .

Very nice thorough job, thanks. Garage wouldnt clean parts as u did.

Thanks for the video, very clear what you need to do. I really struggled to get the bottom bolt/damper undone, I hand to use grips as my spanner just slipped and my car also has an electric handbrake but this didn't effect the job, I just released it with the button first

thank you for this video,I really need a start to finish video and this was perfect..had no problem fitting pads a nd discs exactly as you showed

приятно смотреть как работает специалист

Once i saw you on the bench with the pad assembly i did the same, and located the pads successfully , Many thanks from Cheshire UK BUT the squeal remained, at 10.08 you show a guide being put back in, mine is tight whereas yours is lose. I think the cradel has a fault, will try cleaning to get a smooth operation as you show.

Thank you very much for the video, great job! My wife has an Astra J Sports Tourer 2011 and this helped me service her car including new discs/pads. It has electronic handbrake which I put in "service mode" using a diagnostic computer, then you can push/turn the piston back in to fit the new pads. When I changed to winter tires today, pieces of the shield inside the break disc fell off because of rust. Do you by any chance know how to replace them? Thank you and regards from Sweden.

Do you mean the metal brake disc shield behind the wheel hub and the brake caliber? I haven't change that, but to remove it, i think you have to remove the wheel hub first, and that's a little bit bigger job to do, especially if it's rusted in place. I will have this job coming in some point, but i hope not very soon.

@@kaukolaDIY Yes, its the thin black metal shield that "appears" when you remove the brake disc att approx 03:19. A couple of bolts visible behind the wheel hub in your video, guess I could not see them for all the dirt and rust. Will probably leave it in a shop for this job. Thank you for your response!

the black part of the slide pin is anti-rattle.

The black rubber on the guide pins is to avoid noise from the brake callipers (they can vibrate without it) when you go over bumps ect.. discovered it some days ago.

Thats a really good piece of information , i bought a new overhaul kit from autodoc so new guides and rubbers but they are still tight in the guide hole on the cradle as shown at 10.08 i have a bad feeling its going to be a new caliper, i am suffering brake squeal its not the acoustic wear indicator

I would definitely bring my motor for a service in your garage 🙂

I have an electric handbrake. do I have to set something in the computer after withdrawing the piston? Astra J 1.4 Turbo 2013 year

@kaukolaDIY

Жыл бұрын

I'm sorry, but I have no experience of electric handbrakes. As far as i know, Astra J models have "old style" electric handbrake. Electric motor is not integrated in the brake caliber, like it is in newer Astra K models. That means, that it won't need any special programming or service mode, and it should also adjust by it self, like mechanical handbrake. But, I might be wrong. I hope you can find someone, who really know for sure.

@kaukolaDIY

Hello! Some car models need a scanner tool to set electronic handbrake to service mode. I'm not 100% sure, but in some of those cars, electronic handbrake motor is attached straight to the brake caliber. If i understood right, Astra J models with electronic handbrake, motor is in a different place, and it is just moving the hand brake cables, not the piston it self. So normal brake job should be about the same as with mechanical handbrake. I hope here's someone who has experience of that and knows better.

How does that damper work?

@kaukolaDIY

Жыл бұрын

Damper in rear brakes supposed to reduce vibration of the brake system. How that really works, i don't know. Maybe it reduce braking noise somehow. Some other car brands have the same kind of things.

If the new brake disc comes coated/painted, it has no oil coating on it, the paint comes off after a few brakes.

@kaukolaDIY

2 жыл бұрын

Yes, paint will come off, where brake pad touches. Coating on the disc, keep surface rust away from the other parts of the disc. Next time i would maybe buy fully coated discs. My front discs already have some surface rust in the middle, won't effect to the braking power, but doesn't look so nice.

Not replacing the caliper mounting bolts - bad move. These are Torque/Turn bolts, which mean they can only be used once, as they are stretched when originally tightened. You must use new bolts, torqued to 100Nm, then turned 60-75 degrees. Re-using the old bolts risks having them fail, which can cause a sudden wheel lock up. I know they are expensive, but it's safety first.

Some service manuals says, that you should always install new caliber bracket bolts. Might be, that it's better to have new ones, those are not that expensive.

you don't need to degrease new paint coated brake discs...for an example if you buy such discs from ATE brand in their manual you will see its not necessary..that's why you have layer of paint instead of oil/grease to prevent rust...(degrease only non point coated rotors) regards

I'm not 100% sure, but i understood, that Astra J models with mechanical handbrake, like in my car, have self-adjusting park brake cable system. It doesn't require adjustment after a normal brake job, like discs and bads. It should adjust it self, if i apply and release the park brake lever few times after the brake job.
