21520 Pedal Depressor

OK, if you just need to trigger the brake or clutch switch, you can get away with a less heavy duty product, like the Thexton or the Lisle 48700 throttle tools. HOWEVER, if you need to stomp on the pedal to test the hydraulic system or to apply pressure on a boat ramp, this is THE best product to handle it. The Lisle 21520 is built like a beast, and will handle any pedal pressure you can throw at it. I highly recommend this product if you are working with non-hydraulically assisted clutches (aka "foo-foo" clutches) or brakes. This thing is pretty straightforward to set, and it will not bend a millimeter. With regard to the Lisle throttle tool #48700, that product works great for what it was designed for: precise control of the throttle pedal for testing and diagnostic purposes. It has a 1/2" screw thread that joins the two section of the thin rod together, so I would not recommend using the 48700 for brake or clutch usage beyond just applying some light pressure to actuate the brake or clutch switch for basic testing. If you need to push down hard and hold the brake or clutch, use the 21200 instead.

I used this pedal prop to replace the front brake lines on my 2012 Jeep JK. As per the factory service manual it says to use a prop on the brake pedal, to hold it past the 1st one inch of travel. This will isolate the master cylinder, so that when you disconnect the flexible brake line you won't drain the entire master cylinder. It worked great, saved me a lot of brake fluid and mess. I also used FIRSTINFO brake line clamp to stop the flow from the hard line once the flex line was removed. I purchased those on Amazon as well. https://www.amazon.com/gp/product/B0169LYNLA/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1 A soft rubber plug for the brake caliper when you remove the Banjo Bolt will save fluid as well. I would recommend this item. The yellow end is held on via an O ring. Some didn't like that. Didn't bother me at all.

Use it everyday at work for doing brake inspections on heavy duty trucks, works great and very strong. Only thing they could improve on is the reliability of the yellow piece staying on the connector that slides into the tube, in the past after a year or two we have had some of them come off (you can fix by reinstalling and then pining down the metal so it can't come off again)

I am a Honda Technician. I have just started my career and am currently working on being as efficient as possible. I strive to give the customer a quality experience. A huge overlooked check is lights. You cannot depend on other people to check the lights for you, because it disrupts them during their job. Also not all shops have mirrors to see the brake and reverse lights. I personally check lights on every Multi Point Inspection that comes in. This brake depressor is easy to use and great for checking brake and reverse lights on your own. I have also used it once as a hood prop. I feel any self sufficient tech should have one of these. I have used other ones and this is by far my favorite. I recommend this to any automotive technician, or for people working on cars at home. It would be useful to check lights on personal vehicles without the need of a second person.

This review is for the 21520 TRUCK PEDAL DEPRESSOR, NOT the THROTTLE DEPRESSOR I bought this to use to lock down the brake pedal when power loading my boat onto the trailer. This allows brakes on all four wheels to be fully engaged, not just the rear parking brakes. This makes for a much safer loading process,, greatly reducing the chance of jarring the truck when power loading and allowing the truck to roll back and become submerged, which can ruin your whole day. It is very stout and easy to use and serves the purpose well. The only reason I deducted one star is because the bracket that goes to the steering wheel (or seat frame) is not permanently attached and keeps falling off. To resolve that issue, I simply drilled a hole through the neck of the bracket and through the end of the tube, and inserted a cotter pin.

Great tool for doing a one-man brake/clutch fluid bleeding or flushing. This tool is definitely not light-duty, its stout and should last for a very long time.

The end falls off too easily out of the rod and what holds the foot to the plunger that inserts into the shaft is poorly made and falls off. I drilled and tapped the plunger to accept a machine screw and washer to hold the foot in place. I then drilled a hole (while assembled) through the shaft and plunger to pin it in place. After this modification was done it worked great!

Good price Good product

Had a difficult time finding a depressor that was long enough for a commercial vehicle but finally found this one. Extends nicely but just a wee bit fidgety to correctly extend into place so that it is not loose. Wear a pair of mechanics gloves when retracting so as to not pinch your hand. Very satisfied with the product though.

Excellent quality, very happy

Works perfect on big trucks for brake and clutch pedal. With pedal fully depressed it holds with ease and the plate holds perfect against the seat or steering wheel. Would definitely recommend this one.

I work on trucks and i use it a second person to old brakes

Its good
