Disc Brake Piston Reset Tool

NUMBER BRK-J01

Disc Brake Piston Reset Tool / Brake Press Tool

Very sturdy tool for the safe resetting of disc brake pistons on vehicles with fixed caliper disc brakes / for putting the pistons back into the housing.

Tool is approximately 2 5/8" height plate-to-plate (top to bottom).

Each plate is approx 6.5mm thick depth of tool front to back

(inside) is 2 3/4 inches (69.85mm).

TESTIMONIAL:

When I attempted to replace the front brake pads on a 2001 Mercedes S430, I discovered that my old Piston Reset Tool (the one everyone has in their garage, sold everywhere under different brands for less than $10) just could not do the job. This is because the S430, like many other cars, has Dual Piston, Fixed Caliper brakes, which require a different Reset Tool (sometimes referred to as a Brake Pad Spreader).

When I went to Pep Boys, the salesman told me that fixed calipers are a problem, and he did not have the tool for the job. I went to an independent parts store, which had a tool that had been hanging on their wall since 1979 (it looked like a miniature scissors jack with a long screw), but it could not have been inserted where it needed to be. NAPA had a catalog with a picture of something with a pistol grip on it that looked like it may or may not have worked. The Mercedes dealer can order a tool (MB # 000 589 52 43 00) for $350 that looks like it could be used 1,000 times before it breaks. The JO1 is more than sufficient.

Procedure was simple:

I took the cap off of the master cylinder under the hood, then jacked up the car and removed the wheels. The calipers remained bolted to the car throughout the procedure (of course, if I was replacing the rotors also, I think I would have had to remove the calipers). After removing the retaining pin and spring from behind the pads, I inserted the Reset Tool arms between the small exposed edges of the backing plates on the brake pads. Then I turned the handle on the tool and the arms pushed away from each other and started pushing the brake pads away from the rotor.

Once there was more space I put the arms of the tool against the face of the pads themselves and pushed the pads (and pistons) all the way back. The tools job was done; I then slid the old pads out, slid the now ones in, reinstalled the spring and pins and I was done (after checking fluid level and putting the cap back on the master cylinder).

I feel that I did receive a super tool which does the job perfectly and should last a DIY-er a long time. It does not take up much space in the tool box, and was also the best value option that I found!

Brake Page Measuring Tool

SAE & Metric Sizes: Brake gauge is an 8-in-1 design with 8 sizes (2 mm/3 mm/4 mm/5 mm/6 mm/8 mm/10 mm/12 mm), and both metric and SAE measurement units are clearly marked on the car brake gauge, so you can easily judge the thickness of your brake pads. Colors Distinguish: Green (8 mm/10 mm/12 mm) on the car brake gauge tool means that the brake pads can be used normally, yellow (4 mm/5 mm/6 mm), no need to replace immediately, but wear has occurred, red (2 mm/3 mm), wear has reached a critical level, please replace immediately.

NUMBER MK-PT3747

Wheel cylinder spring clamps,

When you remove the brake shoes from a drum brake assembly, the wheel cylinder pistons are no longer held in place by the tension of the shoes. If someone accidentally presses the brake pedal, or if the internal spring pressure is high, the pistons can pop out of the cylinder, causing brake fluid to spill and air to enter the system.

These clamps provide the necessary tension to keep everything seated while you work.

Most standard sets (like those from T&E Tools or Lisle) have a capacity of about 3.5 inches (90mm).
Materials: They are made of spring steel, often with a black oxide or powder-coated finish to resist corrosion from brake fluid.

NUMBER 13410

Steel wire brush

Designed specifically for cleaning brake calipers during brake pad replacement.

Similar to the Mercedes number 000 589 26 68 00 printed on it.

The angled, narrow head with stiff steel wires allows it to reach into tight spaces on brake calipers to remove built-up brake dust, rust, and old lining deposits without damaging sensitive components like pistons or seals. The ergonomic red plastic handle provides a good grip. These brushes were developed in cooperation with the automotive industry (particularly for Mercedes-Benz service) and are commonly used by mechanics when servicing brakes. Similar versions exist in stainless steel (often with black or green handles) or brass for different surfaces.

Brake Spring Hook

Classic brake spring hook tool (also commonly called a brake spring removal/installation hook, T-handle spring puller, or exhaust/brake spring hook).

This T-shaped design with the long shaft and curved hook at the end is specifically made for grabbing and pulling strong tension springs in tight spaces — most often the return springs on drum brakes (to remove/install brake shoes safely). It's super versatile and also used for motorcycle/ATV exhaust pipe springs, headlight adjuster springs, muffler springs, snowblower springs, and similar high-tension jobs.

Remove and install headlight adjustment and brake springs with this tool. Measures 6 1/8 in. in length. Great for working in confined areas.
