Cache Dust Pump Brake BS2 OTK

Presentation: the rampart against impurities

The cover dust OTK Bs2 (or protective bellows) installs at the end of the rear brake pump, just where the pedal thrust rod penetrates into the master cylinder. Although it appears secondary, it is he who guarantees the survival of your internal joints.

• Original quality OTK : Made in a flexible high density rubber, calibrated to withstand gasoline projections, brake cleaner and chain grease.

• Crucial role: By perfectly marking the movements of the stem, it prevents track dust, sand, water and especially the splashing of gum to infiltrate the spi seal of the pump.

• Compatibility: Designed specifically for the rear braking system Bs2, iconic equipment of group chassis generations OTK (Tony Kart, Kosmic, Alonso, hopefully).

🔧 Installation and maintenance tips

1. Careful dismantling: To replace the dust cover, it is generally necessary to remove the pin or axis connecting the pedal screed to the brake rod.

2. Pre-cleaning: Before sliding the new bellows, impeccably clean the thrust rod. If sand grains remain imprisoned inside the new dust cover, they will act as sandpaper on the piston.

3. Checking the seat: Make sure the wide rubber lip is perfectly clipped in the groove machined on the brake pump body to ensure a total seal.

💡 Michel's trick

"We pay attention to this little piece of rubber than when he is torn, and often it's already too late! The trick: A pierced dust cover lets the gum dust enter the piston and destroy the internal cups of the pump. Result? A brake pedal that becomes spongy or fleeting. My Pro Council: When cleaning your kart in jet or high pressure cleaner, avoid directly tariling this area. The water pressure can dislodge the bellows or lock it from moisture, which would end up gripping the brake control! "
