John is a genuinely honest, kind and knowledgeable gentleman. This is the type of auto repair shop you can feel comfortable sending your friends and family to. Had my car serviced here and he had us up and going in no time. Car had brake issues which he identified and fixed as promised. Not just brakes here. Had another car oil changed and John found some little issues he was able to fix in the process. Stand up guy. Seems like a great family man and proud grandpa as well. Thanks John! read more

I've been bringing my cars here since 1995. Jon is an excellent mechanic and very trustworthy. read more

Took my car in for an issue with the traction control after another shop replaced the axles and the problem started. I took the Sequoia back to the other shop 3 times and was months without my car and they told me they couldn't figure it out. Once I brought it to John he called me the same day and said it was a bad sensor connection and that he wasn't gonna even charge me. Truly a diamond in the rough finding an honest mechanic in LA that knows their stuff. Couldn't be happier and they have definitely earned my future business! read more

Gotta love an honest mechanic. I brought my car in because of an issue I was having with my brakes shuddering. John took a look at it, determined that the problem was a minor warp on one of the brake rotors, and said it wouldn't be unsafe to drive. He told me, "We can replace this, but if it was my car, I wouldn't bother at this point." Didn't charge me a dime for his time, either. I'll definitely be bringing my car back here when I do need work done. read more

My brake warranty has expired but still fixed my car brake problem without questions.

vehicle was 2014 Ford Expedition XL 4WD. Got new struts on each wheel. Owner is very well informed on struts. Even Ford had a hard time figuring out which struts fit this vehicle and screwed up twice in a prior replacement. The guy at the counter is the guy who does the work which means nothing gets lost between the counter and the repair. Based on my experience I recommend this place for suspension and brakes. Price was right. read more

Looking for a great Mancanic or place to have your car serviced? A few weeks I had my 2008 Lexus RX350 towed to this stop. All problems addressed and repaired with no problem. John D is your guy. Thank you so much. read more

This place is FANTASTIC! I had a fuel gauge problem, and John and Brian took my entire back seat out just to check it out. It ended up being something I could live with on a high-mileage car, and they ended up not charging me anything. The guys were polite, quick, courteous and timely. I just moved to the area and was in need of a new mechanic, so I'm very glad I found a reliable one for the next time something major happens! read more

RUDE. Unprofessional. I walk in and wait to get help. Some employee asks if I need help with anything already giving me an attitude. I literally describe the issue that I'm having with my brakes for no more than 20 SECONDS then asks me if I had them done at this shop. I said no, I had them done elsewhere and was looking for help. He said verbatim with an attitude that I wasted "10 minutes of his time". I asked him if there was any help I can get from this shop and asked me to go somewhere else. All I remember was his last name being "Dover" on the business cards presented on the counter. If they have this level of disrespect for their customers imagine the level of disrespect they have working on your car read more

My husband comes here for all service needs for his 2014 Miata. He has no complaints a fair price and quality workmanship.

What you get at this repair shop is reliable car repair, honest and fair, and reasonably priced. The owner and his staff are polite and work hard for their customers. I've been getting my cars repaired here since I moved to southern Ca., and I don't go anywhere else if at all possible! read more

Big shout out to John and his crew over at Stop Brake. My A/C stopped blowing cold on the drivers side of my Armada. Called John, took it down for a estimate and gave me a part n labor price right there on the spot. After breaking down the dash to replace the blender door module the A/C is now blowing cold. read more

Here goes: My truck kept turning over but would not start. I called John at Stop Brake Shops and he gave me some helpful tips to see if I could trouble-shoot it on my own. Unfortunately, the fuel pump went out, so no can do and had to get it towed to the shop for a repair. I called AAA and they towed it, but I was over on the mileage for the free towing. John offered and paid the difference! He had it repaired within the time he promised and it's been running like a champ ever since. He was honest, came in under what the estimate was, accommodated and paid for the difference in the towing, arranged for me to be picked up from the car rental agency when I returned my rental car, and he had my truck back to me on time. If that doesn't demonstrate good business, I don't know what does or what Yelp wants. It seems their filter keeps hiding all of the good reviews and kept the one negative one. (P.S. that reviewer, Justin J. makes a habit of writing negative reviews. Seems like a hater, just sayin.) read more

My family has been going to John at Stop Brake Shop for a very long, long time. John is an honest and fair mechanic, whom I trust implicitly with all of my family's cars. We have sent friends and family to them for years with no issues. They do all types of mechanical and electric work and do it very well. If it's not his specialty, he will know who can do it the job and refer you along. His prices are fair and reasonable for the extensive service he does. Unless it's a dealer specific repair-- our cars go to Stop Brake Shop for everything else! read more

BAD customer service!! Walked in to ask a question, the guy in the office was on his phone talking about his Mother in Law instead of asking me How I could be helped!! I'll spend my money elsewhere. read more

Needed to get my brakes checked out before a long road trip to Utah for the holiday . They checked them out and called me to let me know they were in good shape and they would check all the fluid levels in the car also. When I went to get the car they did not charge me a cent! Not even to inspect the car. We will be bringing our cars here from Now on. Loved their honesty and helpfulness!! read more

John did a great job on my old truck

Awful customer service. Called to get a quote for brake replacement and when asked if I could bring the car in today, was told to come in tomorrow and then hung up. Not the only brake shop in town. Will be taking my business elsewhere. read more

This is my GO TO shop and they never let me down. Had my Chevy in there recently for tuneup. They gave me the straight truth, performed the work in a day and didn't upsell me on work I didn't need. Had my brakes replaced a year ago and low and behold they were just fine! Thanks again John and Brian for the fantastic service! read more

So I haven't had time to get back to Yelp about my first review on Stop Brake Shops, so here goes. Yes on August 20, 2015 John at Stop Brake replaced my husbands window in his truck for no charge. This was a kind thing to do, and we appreciate that. I didn't sign up for yelp to say intentionally say bad things about companies, but I felt we were being mistreated when we changed the fuel pump by ourselves and found out what part it was. I called and talked to John and that's when he offered to fix my husbands window for free, so your A-OK. read more

Replaced our alternator on our Sebring for a really good price, about $300 less then dealer. John was recommended by a friend and was worth the trip from Rancho Cucamonga. read more

What a life saver this place is! After taking my car into the dealer for an oil change they told me I needed over a thousand dollars in "maintenance". Boy was I glad I called John for a second opinion, it saved me hundreds. His shop has been in this location for over 20 years and he's been with it since the beginning. If you're looking for an honest mechanic look no further. I'll never take any of my cars anywhere else. Thank you again Stop Brake Shops, you really are the best! read more

I had my Chevy truck to get a ton of stuff done. I had the transmiission serviced; new hoses, new betls, etc. John was very thorough but most importanly, very honest. I asked about getting new brake pads but John reported that I had plenty of pads and to not change them. His prices were fair and the truck runs like a top. Thank you John. read more

Let me tell you a little story. My wife was driving our 2007 F150 when it started shuttering and missing. Upon taking it to a (will remain anonymous) shop they called me and said we'd been driving it with no oil in the engine and somehow we needed a head gasket. They quoted me a price that was way too low for a head gasket job. Something seemed fishy so we looked around at more shops by my wife's work and found Stop Brake Shops. Took the truck in. Got a call back from John who promptly said it wasn't a head gasket - it was a bad intake manifold! I said nothing to John at all about the previous shop when I took it in to them. John then quoted me a very reasonable, honest price for the work to be done. Bottom line - one shop lied to me to make about $1000 more off of us and John at Stop Brake Shops gave me the truth. They did excellent work and our truck runs like new. To top it off the guys are all great people. They are old school, honest mechanics who know everything about every car. THAT is hard to find these days but there's one right there in Diamond Bar. Kudos guys. You have a customer for life. BTW - I have our 1998 Beetle in there as I write this getting the starter coil replaced. read more

Just got back from seeing John at Stop Brake Shop as I was referred by Hami from ATC next door. I told him that my 2014 Chevy Volt was making a grinding sound from the brakes , but that something could have been caught inside as the grinding noise stopped as I was bringing the car to his shop. He spent time and checked all my brakes for me, and informed me that the pads were nice and thick and there was nothing wrong with them. I am so grateful to them as many shops are not honest and would have done the repair even though it was not needed. So a big thank you to John and I will be using them for my brake repair in the future. Nice to find such such an honest brake repair shop! read more

My rear bumper was misaligned and popped off while I was driving along the freeway on the way to a dentist appointment. When I arrived I told my dentist what had happened and she recommended I visit Stop Brake Shops around the corner. She said the men who worked there are two very kind and honest gentleman who have done a lot of work for her in the past. I took her advice and and she was right. I was thrilled with their service and kindness. They spent 45 minutes in the 100+ heat fixing my bumper and ended up not charging me for it. My bumper looks great and even better, I left with a warm feeling in my heart! Thank you Stop Brake Shops! read more

We've been bringing all of our cars here for over 10 years now and wouldn't think of taking them anywhere else. They are honest, fair priced and really good at what they do. I've recommended them to many and none have been disappointed. Talk to them; you'll quickly see why you can trust them with all your car needs. read more

I have been taking my cars to Stop Brake for at least 15 years. I have always been satisfied with the quality of service I have received. The owner John is honest and fair. I recommend him to all of my family and friends. I will never take my car anywhere else. Thanks John. read more
