Brake band automatic transmission Nissan Cefiro
Purpose:
The brake band in the Nissan Cefiro automatic transmission is used for mechanical braking and engaging the appropriate gears depending on the position of the gear selector.
Location:
The brake band is located inside the automatic transmission, usually next to the drum and clutches.
Design:
The brake band is a metal belt with a friction lining on one side. The friction lining is responsible for transmitting torque from the drum to the clutches, which leads to the engagement of the corresponding gear.
Working principle:
When the gear selector is moved to a certain position, the solenoid valve sends hydraulic pressure to the piston inside the automatic transmission. The piston, in turn, presses the brake band against the drum, creating friction and slowing down the rotation of the drum. This causes the corresponding gear to engage or release.
Types of brake bands:
The Nissan Cefiro can use different types of brake bands, including:
* Single stage
* Two-stage
* Servolents
Replacing the brake band:
As a rule, replacing an automatic transmission brake band requires removing and disassembling the gearbox. This is a complex and time-consuming process that must be performed by a qualified mechanic. Signs of a worn or faulty brake band include:
* Slipping or lack of gear engagement
* Abnormal noises or vibrations when shifting gears
*Transmission fluid leaks
Importance of Maintenance:
Regular maintenance and replacement of the automatic transmission brake band in accordance with the manufacturer’s recommendations is critical to ensure optimal transmission performance and extend its service life.
