ASE A5 Test Prep #1 - Brake Drag & Brake Pull

ASE A5 Task A number 6 "Diagnose poor stopping, pulling or dragging caused by problems in the lines and hoses." Task B #1 and #2 specify drum brake drag. Task C #1 and #2 specify disc brake drag. This videos should clarify what causes disc brake drag/pull, and what causes drum brake drag.

[@OldSchoolNoe]

Update Jan. 14, 2023: After taking the A5 test, this video is helpful with brake drag and brake pull. I did not talk about what can cause tapered wear on a brake pad or what can cause the inboard pad to be worn more than the outer...hint hint.

I just took my a5 and only got 18 right. I'm really struggling 😩

[@OldSchoolNoe]

@@michaelbrock6210 I recommend buying the book "Today's technician automotive brake systems." The classroom manual and shop manual. If you really want to improve you'll read both, can get them for $10 each on ebay, the 6th edition, 7th edition if you can find it cheap.

@@OldSchoolNoe I studied the Delmar book very hard. What's on the actual test isn't really in the delmar book. Do you think the guide you're recommending will cover everything else?

[@OldSchoolNoe]

@@michaelbrock6210 Absolutely! Those 2 books are what taught me the fundamentals. These books are used at the college brakes class. The books are lengthy, but you gotta put the time in!

I would like to thank you for your series of videos. I have failed A5 twice. I saw your videos. Took the notes and reviewed these videos multiple times. I just passed the test with a 52 score out of 55. Thank you so much

Man, this is one of the best videos I seen so far on KZbin. This is going to help me a lot. I will be going to take the A5 test next week on Saturday and this combined with my studying definitely going to help me out a lot great video.

Hey man I just wanted to let u know that I take the A5 Brakes test today i did pass My Score was 38 out of 45 so thanks you for making this Video to help people out it Definitely help me out A lot

[@QuickScopingFisH]

Thank You!!! These videos helped me pass and make more money 🙏

[@rickyracoon911]

Here for review for my A5 recert. One of the best things I was taught about before I took my A5 was that on the ASE test always remember. technician A and technician B are never going against each other. They are simply a true, false/ true,false question.

[@OldSchoolNoe]

Interesting!

[@technomage6736]

Fantastic videos! Very helpful. Thank you so much for sharing! Just passed my brake test today! 👌💪 I appreciate you mentioning the "restriction" thing because this initially threw me off on practice tests.

[@reneflores8681]

any chance you are able to give the answers out for those practice questions you had at the end of the video?

[@James-fl2ug]

Hey man can how can I get most of the A5 electrical diag schematics right? It seem soo confusing. Can you give me any advice on how to know which X,Yor z would be open or closed

[@mike-yp1uk]

Nice

[@petersobik2162]

The vocabulary is really important. That’s where people get confused and thrown off

[@OldSchoolNoe]

give me 2 examples please. I recently uploaded a test prep series for the A7, and "restricted" and "plugged up" were 2 words that could have caused confusion when it came to system pressures. The test did not give conflicting answers and all questions were asked in a clear manner. Same with the A5, once you understand the concept of brake drag/pull, you'll be fine no matter what vocab the test throws at you.

[@petersobik2162]

@@OldSchoolNoe I haven’t tested yet that’s how I’ve found your videos bc I’m about to schedule for some test and I think I’m gonna take A5 first I’ve been doing this for over 20 years professionally but never could benefit financially where I’m at but now that I’m in my 40s I think it’s time to get some of my ase certs. But what I meant by the vocabulary being confusing,let’s take restricted for example. From watching your videos it looks like restricted could mean completely no flow of fluid or very little but I guess I’d have to see the questions with the multiple choice answers to make it easier for me. I did get the questions right you included in your mini series.

which suspensioin component casusing pull during breaks?

[@OldSchoolNoe]

Can be worn bushings on the control arm. Worn ball joints too, but you'll notice a pull on acceleration too.

[@dcsbeats739]

Can I know the answers to the questions at the end of the video please?

[@OldSchoolNoe]

For the first question, most likely it is not due to a faulty master cylinder or worn brake pads. In theory, a leaking brake hose on the left will cause poor stopping ability on the left, therefore the vehicle will pull to the right, because the right side will have 100% stopping ability. The answer is B. If the caliper piston is seized on the right side, the brakes will not activate on the right side. Question 2 the answer is C. A bleeder is valve is used to remove old fluid and purge air out of the system. If its binding (hard to loosen), it will not cause brake drag. 3rd question: A faulty master cylinder will not create hydraulic pressure, therefore it will not cause brake pull. A brake pull is usually caused by a defect in one side (left side or right side). A faulty metering valve affects both sides in the front, most likely it will not cause a pull. A faulty drum brake self-adjuster will not adjust as drum brakes wear. This will cause the brake pedal to travel further as brake shoes wear. Theoretically, if the wear is severe on one side with bad self-adjusters, there could be a pull, but this is not the most likely. The answer is D. A brake caliper will cause a pull when faulty. Faulty meaning not activating, not moving, seized.

[@dcsbeats739]

@@OldSchoolNoe thank you for the answer and explanation

[@what_sgood2603]

Hey in the test they don't specify if the seized part is resting or applied. They use the vocab of "Frozen" or "Seized". It is confusing that your video does not use the same vocabulary.

[@OldSchoolNoe]

I noticed this, but when I took the test, I had no conflict in answers. For the most part I noticed that seized means stuck in the resting position. I don't think I saw the official test use "frozen" as a descriptor. Hope this helps!

[@ajtorress_21]

Hey I had a question so I’m planning to take A5 test I was reading the comment n saw someone commenting about how on there test they didn’t explain if the calipers piston and brake hose was completely blocked off or partially so how would I know when I’m reading the question if they mean completely blocked off or partially thank you

[@OldSchoolNoe]

I've taken 6 ASE tests, and most of the time I've noticed that they mean completely blocked off. They won't try to trick you and give 2 possible answers. I would say don't worry too much about it, there's at least 1 question about "restrictions."

[@vegasking7022]

How many questions on the A5 test? How many did you miss?

[@OldSchoolNoe]

I scored 41 out of 45. There was a total of 55 questions, 10 did not count towards score, but i do not know which ones.
