Hi this is not my vehicle. I am I college student at unoh and was ask why did Chevy use leading / trailing brakes on their full sized silverado pickup?
I learned in class that leading trailing bakes were used on light vehicles or front wheel drive vehicles due to less stoping power needed at the rear.
Could you tell me what years and why Chevy used this?
Like I said the teacher said it was only used a few years but wants us to find out why. Thank you
Do you

Didn't I answer this yesterday? If your teacher was bright enough he would know that when a vehicle is manufactured there are cost factors involved to make the most money out of a product. As this is a light duty vehicle it is done for cost and as long as it passes safety requirements at the time they make it that way. Tellhim to look into newer products not ones that are 20yrs old asking questions like that. He ahs aproblem contact me directly

Well buddy there's no reason to get smart. I obviously did not get the answer I was looking for. I did not figure cost would be the answer he was looking for being such a simple answer. My teacher knows the answer and ask the class to get an answer. I looked all over the Internet and couldn't find a specific answer so I thought I would ask the "experts".

Wel having worked in engineering for 32 yrs I can tell you that is the reason although your teacher may not aggree. This I s an old system that hasbeen inuse for years. And the only anser you will find is on wikepdia which explains what it is and not WHY a manufacturer put that particular system in their vehicles. By the way we as mechanics dont know the answers to questions like this anyhow as we just fix these things not design them as alot of times we are not in aggreement with the way cars are built. If your teacher is going to give you a question like this he shold give you a hint as to wher eyou CAN find an Answer. Unless you have an engineer that has experieince or has been a Brake engineer then you are looking at a dead horse so to speak. But do me a favor show your teacher the last response I sent see what he says. He'll laugh probably. Having repaired vehicles for 48 yrs today's vehicles are much beter suited to the driving that people do. Althought they screwup still trying to fix problems by replacing parts prior to actualy checking for codes, fuelpressure etc with out the knowledge of how to do it.

Here is the only thing that we have in our manual about leading /trailing brakes

Some vehicles are equipped with leading/trailing brakes, identified by adjuster screw hole in backing plate, located above hor
axle. All other models are equipped with dual servo brakes, identified by adjuster screw hole at bottom of backing plate.

Brake assembly consists of backing plate, brake shoes, return springs, automatic adjusting assembly and a wheel cylinder.

Automatic adjusting assembly consists of an actuator lever, return spring, actuator link, adjusting screw and spring. Automati
through movement of actuating lever and secondary shoe.
