How to change front brake discs and front brake pads on OPEL ASTRA H TUTORIAL | AUTODOC

[@lennyh500]

Just to clarify, "end bit #7" is a 7mm hex. T45 torx bit is a worryingly good fit when you're working blind : ( And yes, I did take the reservoir cap off first. Good vid, but : )

[@autodocuk]

Thank you for your feedback! We have used a 7mm hex head for dismantling the caliper guides. Stay home and stay tuned with us! Best regards, Autodoc Team!

I’ve put my new discs on and tightened the calliper bracket, when I move the brake rotor I have a loud screech as if it’s binding. I’ve tried taking it apart again to clean then put it all back together including the calliper with new pads and still there’s a bad screeching sound. Any ideas what this could be?

[@ianlawrie919]

Very informative 🤗

[@solitaire5142]

No anti seize on the rotor? No copper paste on the pads? No torquing to spec?

[@mariusmarius9977]

[@PogoLoco88]

Dose any one know the torque specs

[@Carpet-m5j]

Not recommended this video ... missed out lots of detail steps for the who is going to try for first time

[@tilly0191]

Make sure to re torque all bolts as they would have been in the factory and copper grease brake pads to stop sqeaking mainly on older cars though.

Thank you for the feedback! We are currently working on creating a wider range of tutorials including the one you mentioned. Stay tuned and follow our latest updates. Best regards, Autodoc.

Either the brake fluid reservoir cap or or bleed valve should be opened prior to pushing back the brake cylinder. You are likely to blow the master cylinder if this is not done.

[@webjockel]

You dont get away with that...

[@shropshirehistory908]

I’ve done all this and removed the reservoir cap and now my breaks don’t work at all they have gone really soft and pedal goes to the floor, would this mean that I now have to bleed them?

[@milogaming5556]

@@shropshirehistory908 yea just bleed them thats all you need to do

[@shropshirehistory908]

@@milogaming5556 are you sure!? because with not taking a pipe off and not loosing any brake fluid I really shouldn’t have too….so that could be another problem don’t you think!?…you sure I don’t have to test the abs system and make sure there isn’t an air leak in the system!? Or maybe it could be the master cylinder diaphragm has flipped inside out, or maybe it has a hole in it and pushed air back in the lines, technically that shouldn’t happen if the lid off the reservoir is removed which it was or bleed nipple opened….so I’m going to say no bleeding them wont be all I have to do!…thanks for your comment but i don’t think it’s even an option as they shouldn’t need bleeding so I’m going to say I have a knackered master cylinder so a 2nd opinion off someone who knows about cars an abs systems would be better but thanks.

Making these videos while skipping some crucial steps is very irresponsible. Or is this the plan in the first place to lure people to repair their cars afterwards in the service?

[@autodocuk]

Thank you for the feedback! The video is informative and shows only the general principles of the constitution and the operation of the car and it is in no way to be taken as a manual for repair and maintenance. Best Regards, Autodoc

For example?

[@milosmilekic6636]

I still don't understand which bit extension is used to remove the calipers, hexagonal No. 7 or Torx T45. Can anyone clarify it please?

[@autodocuk]

The calipers are unscrewed with a 7mm hex wrench.

[@milosmilekic6636]

@@autodocuk Thanks a lot!

[@robertfric6010]

Great videos, really like them! One question I have, would 308mm break disc (from Astra H 2.0T) fit on my Astra H 1.8 VTi (original is 280mm disc)? Because calipers of both engine config seems to be the same size - 1 piston of 57mm. Thank you for your thoughts

[@autodocuk]

Thank you for the feedback! We strongly recommend you to visit a specialized car service center. Best regards, Autodoc.

Can anyone tell me the size of the bolts holding caliper mounting bracket (the one you used socket 18). I can't find them anywhere.

Aren't you meant to clean the new disc to remove the protective coating from the manufacturer?

[@mercedes_and_more]

Was about to write the same, de-greasing the new discs is a VERY important step that shouldn't be missed. Shame as otherwise a super clear demo of this job

[@derekmills1429]

Are you not meant to remove rust and debris from the hub face before putting in new discs and clean up the caliper carrier and slide bolts as well .

[@bladehea]

No u dont have to remove coating

[@mohitl13]

Hello! When is a good idea to change the brake fluid? Also, can you make a video on how to change the antifreeze and the brake fluid on the astra h?

[@mohitl13]

Your comment doesnt seem to make any sense

[@autodocuk]

Hello! The break fluid should be changed every two years. Subscribe to our channel and stay tuned for updates.Best Regards, Autodoc.

[@mohitl13]

autodoc.co.uk okay, thank you. will you make a video soon on changing the coolant and brake fluid on the astra h? when changing the coolant, is it necessary to flush, or can you just empty and refil, then move air locks. Thank you!

[@autodocuk]

+M LV Thank you for the feedback! Stay tuned and maybe we will release the video that you are looking for. Flushing the cooling system is desirable but is not compulsory. Best regards, Autodoc.

[@mohitl13]

autodoc.co.uk okay, thank you! Can you make a video on changing the coolant by just draining it out, so not flushing. also, does it require 3 litres of water and 3 litres of coolant? thank you :)

[@novakae1]

those brakes are ABS righ ?

[@autodocuk]

Thank you for your feedback! Thats right, those brakes are ABS. Best regards, Autodoc.

[@Corfine]

Maybe slow down video bit fast you need tool for disc

[@albertoruiz9829]

Hi autodoc, my astra has brakes in good condition but yesterday they went pedal is now hard. Wagt could be the cause? My adtra is the same as the video

[@autodocuk]

Thank you for the feedback! Unfortunately, it is hard to answer your question unambiguously. There can be plenty reasons for this. Please, contact the Car Specialized Service for full diagnostics and revealing of the reasons for the issue. Best regards, Autodoc.

[@straightblast569]

Were the grease and cleaning it this was one of those doggy mechanics who don't do a proper job can't believe mechanics nowadays have no skill and no pride in the work just want to make quick money this happens Lot in Britain scamm traders

[@wasimc4683]

Now I dont know much about cars but I sure you're meant to bleed or drain the brake fluid beforehand no ..

[@autodocuk]

Thank you for your comment! You do not need to drain the brake fluid when replacing the brake disc and pads. Best Regards, Autodoc team

[@straightblast569]

Those brakes will sqeuk
