Brake Inspection
When checked all four wheels for brake inspection, it was disc brake with callipers, the front were non vented the back was vented disc type.
The Brake pads had enough treat left on it but the rear brakes were worn unevenly and the inside of the disc had a few chips in it.
Carrier plates need replacing or servicing
30mins to 1 hour is enough to do a full brake service, maybe 90mins if you are new to it.
3 Different drum brakes
Servo: Its not connected at the bottom. The brake servo unit intensifies the force of the driver’s foot on the brake pedal. If the driver starts braking, the connecting rod moves left, pressing the seal of the double valve against the valve seat, thereby closing the connection between the two chambers
Simplex: the Simplex drum brake has the trailing shoe to the right and the leading shoe to the left. The shoe is called leading, if a certain point of the rotating drum passes the spreading mechanism (in this case the wheel cylinder) before passing the anchor-pin side. This creates a wedging effect, which produces a relatively large braking force in spite of only little pressure on the brake (self enhancement). With the trailing shoe the effect is the opposite.
Duplex: The Duplex brake has two leading shoes in the roll direction (i.e. on the left). Reversing however, causes these to wear.
Good overview
ReplyDeleteA bit of a mix up, the Brake booster is some times called a Servo, in our context it is a Drum brake arrangement similar to the Simplex but the lower Anchor is not fixed to the Backing plate. Would be good to hear how you check a drum brake and a disc brake
I had my car on a auto service shop and they noticed that I need to align my wheels. Uhh.. Now I learn to regularly have an alignment and brake check.
ReplyDeleteWell done on comparing the drum brakes,it really is important to have a regular brake check or other car maintenance for good driving and travel.
