The problem is that you make catastrophic mistakes when installing brake discs, you MUST NOT clean the hubs with metal brushes in no case!!! - that's what the right tools are for. DO NOT apply any paste or other shi*ty "protector" to the surface between the hub and the brake disc. You MUST NOT measure the disc on its bell side (how the fu*k u have to correctly measure beating on the brake disc when it's not correctly measured????) - you have to do it on the edge of the friction surface of the disc for the measurement to be correct ... - this is a fu*king joke, how can you record a video in public about making mistakes when assembling brakes, if you can't do it yourself . AUTO-DOC you suck... and making people moore more ignorant than they are now....
Yea, at 6:12 it says that some guide pins need no lubrication. I was using silicone paste on this type. Thank you. Makes sense since the grease would get on the threads. I think that's why my rear calipers are making noise, they're loose. Again, thanks!
i think the issue with greasing that type is that dirt/sand/grit will stick to the grease, and then its like sandpaper. The other system they showed seals the grease inside with the harmonica looking rubbers
ATE actually sells an acid free paste for this application. In northern countries, not using any lubricant on the guiding pins will for sure lock up the brake calipers 😅
Brakes pay 1.5-2 hours taking all of these factors into consideration, but 95% of technicians will shortcuts to reduce the time to 30 minutes to 45 minutes while still charging the customer 2 hours labor.
@Chris Sikora Well, that's on them. But a large portion of the things talked about in this video are done by most mechanics I know. (including myself) I don't appreciate the hate towards mechanics as a whole. I mechanic screws up don't blame us all please..

Why is a mistake to lube the sliding pins for the front brakes ? minute 06:09 ? its nice to place also the reason and what will happen if we lube it. I can say that i lube them and now the brakes are running like brand new! without lubing the sliding was robust and not that even, even with new boots.
@@autodocuk this technical aspect is TABOO, it doesn't exist and nobody knows anything about it :) It seems that you as well throwed it out without any reason or explanation.
Hi ... I have a skoda fabia 2004 It suffer from a mechanical problem that local mechanics haven't figured out the cause yet The car shakes back and forth when I lift my foot off the gas pedal (the shake is at its top in first gear and weakenes in higher gears) I replaced two mounts but the shake didn't go away .. any help!
When cleaning rust off of hubs it actually does 2 important things: #1: ensures proper runout #2: it improves conductive heat dissipation which will increase the longevity of wheel bearing and rotor lifespan! Clean metal transfers heat faster than rusty metal.
@@makantahi3731 because patroleum products anywhere around the brake fluid is a no-no, so if you are going to spray the brakes with it, it is not a good idea to spray it in side the dust boots on the wheel/ caliper cylinders
those are the same on my bmw x1 e84, in the manual says those must not be greased, just cleaned..I did found brake dust stuck on them, pads did not return properly, uneven wear...added grease twice and they perform nicely. The rubber boots wear and get sticky on high temp, brake grease help it slide, it works for me ! treat it as the factory advice to change oil at 15-20 k :))
Generally, caliper guide pins should be lubed -- and only with silicone-based grease. I use 3M silicone paste which is also great as a general lube for non-metallic parts. Petroeum-based lubes will degrade the rubber boots.
Not every tech follows this because of certain circumstances due to customer wanting their vehicle done within 30mins or less, parts department not providing the correct parts or hardware needed to properly perform the job, service writers being stupid and rushing techs to get the job done.
If you buy anything brake related and have to return because it takes so long to arrive, don`t expect your money back they will deny receiving it even thought it as to be signed for. it will completely disappear and you will be out of pocket.
Exactly. The only other thing is you shouldn’t mix dot 3 with dot 4 if it’s a car that requires dot 4, but other than that, you should be fine mixing certain different brake fluids (of at least equal or higher, but not lower, grade than the car requires.
@@AAP0000 only difference between dot3 and dot4 is te boiling point. Dot5 have silicon in it and will ruin the system if it's not recommended to use it.
Brake cleaner acts aggressively against anything that's hydrocarbon, and as rubber is made of that it'll be damaged over time. Also, do NOT use it to clean painted calipers as the paint will get wiped out by the product
i thought brake cleaner was supposed to be safe on rubber parts as brake systems have a lot of them? I wouldn't use other cleaners but i thought specifically brake cleaner is safe
You got the hub paste all over the wheel studs. Major no no. This will not allow the lug nuts to be properly tightened, and severely over tightened, breaking the stud and damaging the wheel and maybe come lose. The FIRST thing I do is to flush the entire hydraulic system. Then I will open the bleeder, remove the caliper and hold it upside down and shake it while under pressure to help remove any rust that sits in the bottom of the caliper.

Awesome!!!🙌
how you change a brake caliper with electroic parcking barke ? you have any tutorial for that please ?
To answer your question, we need more information about your vehicle.
2:26 your piston dust boot is torn on the bottom part.
it needs to be replaced
Bruh did you watch the video?
You could add copper grease on caliper brackets so brake pads move much better.
Smile
it is good for high temps because it can not seize,(sparkplugs, screws on exhaust) but can be washed easely by water , and what if it comes on disc
the issue i see with this is that dirt/sand/grit will immediately stick to any grease and then in my opinion its worse than having no grease at all.
Yes, you can apply grease to the caliper brackets, recommendations for what kind of grease to use should be found in the car repair manual.
Nope dirt sticks to it and seizes the pads

mee too, just keeps the dust away...it will solidify in years, previous owner did not do brake jobs often

@@autodocuk this technical aspect is TABOO, it doesn't exist and nobody knows anything about it :) It seems that you as well throwed it out without any reason or explanation.
Since it says "don't need to be" instead of "you must not do that", then it probably won't happen anything if you lube the sliding pins 🥴
@@SanKraN87 Also, I think it is because the pins go through rubber material, they don't have direct contact with metal, so no lubricant is needed.

Hi ... I have a skoda fabia 2004
It suffer from a mechanical problem that local mechanics haven't figured out the cause yet
The car shakes back and forth when I lift my foot off the gas pedal (the shake is at its top in first gear and weakenes in higher gears) I replaced two mounts but the shake didn't go away .. any help!
front strut mounts/bearing, loose nuts on top ? cracks when wheel turned ? bushing/swaybar ? worn wheel bearing ?
There can be many reasons and without proper diagnostics, we cannot advise anything, please contact the service.

Could be play in the drive shafts, but it's impossible to say for sure without having seen the car
Its the two Rubber mounts in the Front Suspension where the Motor Torque mount sits

La pâte ATE pour cylindres de freins utiliser pour guide pin ??
Bonjour!
De par leur conception, il n'est pas nécessaire d'utiliser de la graisse pour les guides.

Is brake cleaner a patroleum product?
typically it's a mix of ketones so no
why
It is not possible to answer your question. This information must be found on the packaging from the manufacturer.

And when you're finished, pump your blessed brakes to take up the slack. Don't ask me how I know
There are lesser and lesser mechanic will repair in this detailed
that job is for you, to do it easely with no hurry, i did do it , all 4 wheels, it took some 4-5 hours to do it properly
Is there any harm in lubricating the caliper guide pins in the brake system shown at 6:10.?

@@camaroblackmatte What kind grease do you use for the glide pins? Silicone basic grease? Or ceramic grease
I put silicone grease on mine! Sometimes provided with the brake pads
Generally, caliper guide pins should be lubed -- and only with silicone-based grease. I use 3M silicone paste which is also great as a general lube for non-metallic parts. Petroeum-based lubes will degrade the rubber boots.
i had provided in kit grease with new guide pins and rubber boots

That's actually true, i like your own perspective view of life
or to be cheap
Replace calipers when broken

jeah, all done
U can mix dot3/dot4/dot5 together but never any on them with dot5.1, that creates a mess in ur brake fluid sistem
