What should I do if the disc brake of the Giant ATX770 D 10 is lubricated?

I'm experienced with this problem because I've been in the same situation as you.

The first floor is a bit troublesome, in fact, as long as you remove the disc brake (unscrew the two hexagonal screws) and use something like sandskin paper to grind the two small pieces in there (to order the piece) and then wash them with dish detergent (the effect is more obvious with Mr. Wittmann), and then put it back, wipe the oil in the clamp (the thing you removed) also clean, and finally wipe the disc with a napkin (Mr. Spray is better), you can see that the napkin has black oil on it, and then install the clamp and you're done.

The original braking effect will not be restored immediately after installation, because the lubricating oil is generally not easily removed. Don't worry, be careful when riding, after a while, the braking effect will gradually improve due to the wear and tear of the lintel, until the initial effect. The above is my own summary of DIY practices, you can really give it a try, although it will be a little tiring, but there will be a great sense of accomplishment after success, and you should know your car.

If you are not sure, please consult a professional.

Lubricating oil? Try removing the lings and soaking them in gasoline. There are also discs scrubbed with gasoline.

Gasoline is used to remove oil, and the effect is still good.

If you have the technology, it is better to remove the disc and the liner and clean it with gasoline.

If you have it in the clamp, wipe it a few times with gasoline and you're fine.

The only way to get rid of it once and for all: take it apart and clean it!

I haven't encountered it, I'm sorry.

Summary. You can loosen the screws of the rear oil brake, carefully observe whether the disc is rubbing against the left side or the right side, if the disc is rubbing against the right side, push the clamp to the right side, and evenly give the gap between the disc and the right side.

You can loosen the screws of the rear oil brake, carefully observe whether the disc rubs against the left side or slips or rubs against the right side, if the disc is rubbed against the right side, push the clamp to the right side, and evenly give the gap between the disc and the right side.

Pro, if the disc is rubbed with the left side of the plate, then push the clamp to the right, and the gap between the piece and the disc will be evenly given to the left side, and the thrust should be uniform when adjusting, pay attention to the piece to be parallel to the disc sensitive fiber, after adjustment, we will force the two fixed screws of the clamp, you had better put the disc in the middle of the left and right pieces, to ensure that the distance between the left and right sides of the plate and the disc is equal.

Dear, it is a relatively common problem that the Giant oil disc brake has no brake after the oil disc brake is changed, and this situation is generally caused by improper oil disc brake oil change.

Hello dear, 1. The rebound caused by the piston being stuck by fine sand and other debris is not working. Solution: Disassemble the brake caliper to clear the debris around the piston.

2. The rebound is ineffective caused by the lack of oil at the brake hand crack and the axle pin of the return handle is stuck by debris. Solution: Remove debris and apply lubrication to the axle pins of the brake lever.

3. The rebound is ineffective caused by the reduction of hungry oil in the brake belt in the oil disc assembly. Solution: Replenish the brake fluid to the oil disc assembly in time.

4. The rebound caused by the blockage of the oil circuit of the oil disc assembly is not effective. Solution: Dredging the oil circuit in time can be solved.
