Hello guys, today I will change the brake disc, pads and the brake caliper on a Renault Trafic identical to the Opel Vivaro and the Nissan Primastar.
Before the video starts: once again the warning that you do this on your own responsibility and I am not liable for any damage to the vehicle or for injuries. This video is only meant to help you.
When you have jacked up the car and secured it against rolling, you can remove the wheel. Before you remove the brake caliper, I would first loosen the brake line, because this is easier when the brake caliper is still attached. It's possible that some brake fluid is already coming out, so put a catch container underneath. Then we tighten the brake line hand-tight again, so that not too much brake fluid leaks out.
Then we will need to unscrew the brake caliper. There are two screws here on the backside. Once you have those out, the caliper can be tapped a little loose and then removed.
Now you need to unscrew the caliper bracket. There are the two bolts here on the back. They're often very tight, so it's helpful to spray those with a little penetrating oil beforehand.
When the bracket has been removed, the screw here can be unscrewed, this is a Torx, but you have to be careful that you do not breake it. Then you can remove the brake disc.
Now all contact surfaces must be cleaned, so at the wheel hub where the brake disc contacts, which is particularly important so that the brake disc is straight and does not beat when braking, then also here where the brake caliper contacts and also at the caliper bracket itself where the brake pads contact.
Then I have here new bushings, which should also be replaced because they get stuck and then you have a problem again, there's a set, so the bushings, the rubber sleeves and the paste with which you have to lubricate properly, so that no moisture can get in. When you insert it, make sure that the rubber sleeve is also really tight, so it must snap into place a bit.
Then the new brake disc can be screwed onto the wheel hub.
Then the caliper bracket, where the brake pads will contact. Lubricate the contact surface with ceramic paste, but none of it should get on the pads themselves or the brake disc.
If you have to replace the brake caliper, you can now screw the brake line from the old caliper to the new one. We have already loosened it, so that should not be a problem. Again, put something under, because brake fluid drips out.
Now the new brake caliper can be screwed on again. Always tighten all screws properly.
So, now that everything is reassembled, all that's left to do is bleed the brake and fill the caliper with brake fluid. For this, this bleeding valve must be opened, it does not have to be screwed out, it is enough if it is loose. Now put a piece of hose on it, any that fits.
For bleeding you need a second person, who presses the brake and pumps repeatedly, until brake fluid comes out of the hose. If a continuous flow comes out of the hose and no more air bubbles appear, then you screw the valve shut again.
Now you can remove the hose, tighten the valve with the ratchet and put the protective cap on it.
Now, of course, the brake disc and pads must be replaced on the other side as well, because with the brake you always have to do both sides. So again wheel off, caliper off, caliper bracket off, brake disc off, and so on. On this side you want to use the caliper again, I suppose, so you have to push the pistons back, otherwise you will not get it onto the new disc and pads. You can either do this with a large pipe wrench, but there is a risk that you will jam the pistons, or you can take a piece of wood like I did and push it back with two screw clamps. The brake fluid reservoir should be opened beforehand, because it pushes brake fluid back into the reservoir. Assembly of the brake is then the same as already explained.
Now you check again whether you have really tightened all the screws, have not forgotten anything. Especially with the brake, this could be very dangerous. And if you have done that and you are sure, then you are almost finished. Now you only have to fill up the brake fluid reservoir to the maximum level, because you lost some earlier bleeding the brake.
Well, with that you have successfully replaced the brake caliper, brake discs and pads on your Renault Trafic, Opel Vivaro or Nissan Primastar. I would advise that you drive the first few meters extra carefully; if something did go wrong, you will notice it. Because, as I said, a fault with the brakes will be serious. It may also happen that the braking performance is not yet so good on the first kilometers, because the brake must first grind down a little.
I hope the video and my explanation helped you. As a small tribute to my work, I would really appreciate a thumbs up, a comment and a subscription. Then I wish you a lot of fun with the repairs, saving that workshop money, and then I'll see you next time. Ciao.
