Delivery arrived on time and in perfect condition. (Brake piston return set, 13 pcs. Sales by Oxid7 GmbH). Problem-free use in the above two vehicles. Adapters fit problemlos.Werkzeug makes a high impression. As the picture is all well ordered in the case. Operation is eigendlich for every hobbyist self-explanatory, the coupling plates you can by simply applying the brake pistons determine. No bending or sliding down the spindle or plates, even in the T5. The brake piston can push back soulful. If this spindle the brake piston can not be pushed back easily the brake cylinder is either way overdue for an overhaul. For rust problems some Vorrezensoren I can not say anything yet, because the part is only 1/4 year old. I'll be surprised when the case is opened next year. The Gemurkse with homemade rear plates is finally over. For little money, the work done easily. Should have my brake piston return rate already buy a lot more.
