About this product

OPTIMAL brake pads (12121) deliver consistent stopping power through a friction compound engineered for low noise, reduced brake dust, and stable bite across a wide temperature range. The pad compound characteristics — Fitting Position: Rear Axle, Thickness [mm]: Silicone, Steel mm, Width [mm]: 95, Rubber mm, Height [mm]: 37, Carbon mm — are selected to balance progressive pedal feel with minimal wear on mating discs. Designed as a direct replacement for TOYOTA applications, these pads slot into the original caliper bracket without modification. Cross-references OE part numbers: 025 238 1616/W, 0446602020, 0446602040, 0446602070 and 59 more. OPTIMAL brake friction products are validated in independent dynamometer tests and are used by authorised service centres throughout Europe. Brake pads typically need replacing every 25,000–50,000 miles, depending on driving style, vehicle weight, and whether you drive mostly in urban stop-start traffic or on open roads. Watch for squealing or grinding noises when braking, increased stopping distances, a pulsating brake pedal, or a brake warning light on your dashboard — any of these signals that the friction material is worn to its minimum thickness. Brake pad replacement is a moderate DIY job requiring basic hand tools, a jack, and axle stands — allow approximately 1–2 hours per axle for a first-time installer, less if you have experience with caliper removal. When choosing brake pads, look for ECE R90 approval (mandatory for road use in Europe), copper-free formulations for environmental compliance, and a shim or anti-squeal backing plate for quiet operation. Replacing brake pads promptly prevents scoring and heat damage to the more expensive brake discs, saving significantly on repair costs in the long run. Every part is dispatched from our UK warehouse with a 30-day money-back guarantee and free hassle-free returns.

Brake pad set buying guide

Why replace this part?

Brake pads are the primary friction component in your braking system. As they wear thin, braking performance deteriorates, increasing stopping distances and putting your safety at risk. Worn pads can also damage brake discs, leading to more expensive repairs.

Signs you need a replacement

  • Squealing or grinding noises when braking
  • increased stopping distances
  • brake pedal vibration or pulsation
  • dashboard warning light
  • visible pad thickness below 3mm
  • pulling to one side when braking

When to replace

Every 30,000–70,000 miles depending on driving conditions, pad material, and vehicle weight. City driving with frequent stops wears pads faster than motorway driving.

Installation difficulty:Moderate — requires basic tools and mechanical knowledge
