A Guide to Replacing the Disc Brake Calipers on Your 2007-2009 Chrysler Aspen
Everything you need to know about choosing the right new aftermarket brake calipers for your Aspen.
- A seizing or sticking caliper is the most common failure, causing pulling, brake drag, and uneven pad wear.
- New aftermarket calipers with corrosion-resistant coatings (from brands like Powerstop or Raybestos) offer better longevity than uncoated parts.
- Always replace calipers in pairs (both fronts or both rears) and install new brake pads and fluid at the same time.
- Brake bleeding is a critical final step that can be tricky; ensure it's done correctly to remove all air from the system.
Is Your Chrysler Aspen Showing Signs of a Bad Brake Caliper?
A failing brake caliper is a serious issue that compromises your Aspen's ability to stop safely. Unlike brake pads, which wear out regularly, calipers are designed to last a long time, but they can fail, especially on vehicles over 100,000 miles. Common causes of failure include rust and dirt buildup causing the caliper pistons to seize or stick. This can lead to either the brake staying partially applied or not applying with enough force.
Key Failure Symptoms
🎬 Watch: A mechanic's guide to diagnosing a seized brake caliper.- Vehicle Pulling to One Side: When you apply the brakes, a seized caliper can cause the vehicle to pull sharply to the left or right.
- Brake Dragging or Overheating: A caliper that doesn't release properly will cause constant friction, leading to a hot wheel, a burning smell, and poor fuel economy.
- Uneven Brake Pad Wear: If you notice one set of brake pads is worn down significantly more than the other, it's a strong indicator of a sticking caliper.
- Brake Fluid Leaks: Puddles of fluid near your wheel could be a sign of a leaking caliper due to failing seals.
- Spongy or Soft Brake Pedal: This can be caused by a fluid leak or air getting into the system, sometimes from a faulty caliper.
- Grinding or Squealing Noises: While often caused by worn pads, these noises can also point to a malfunctioning caliper.
Vehicle-Specific Issues and Recalls
While there are no major recalls specifically for the Chrysler Aspen's brake calipers, NHTSA issued a recall (07V-442) for some 2007-2008 Jeep Grand Cherokee and Commander models, which share a similar platform. This recall was for improperly manufactured front calipers that could break. While the Aspen was not included, it highlights the importance of using quality replacement parts. Owners in online forums have reported issues with caliper pistons on the Aspen failing to retract during brake jobs, which is a clear sign the caliper needs replacement.
Choosing the Right Aftermarket Caliper for Your Aspen
When replacing a caliper on your 2007-2009 Aspen, you'll primarily be looking at new aftermarket parts. OEM calipers are very expensive, and while remanufactured parts are an option, the quality can be inconsistent. New aftermarket calipers from reputable brands often provide the best balance of quality, reliability, and price.
Many aftermarket calipers come with a protective coating (such as zinc plating or powder coating) to resist corrosion, which is a major cause of caliper failure. This is a significant advantage over uncoated original parts, especially if you live in an area where road salt is used in the winter.
Aftermarket Brand Tiers
- Performance/Premium (Powerstop, Raybestos): Brands like Powerstop are often seen as an upgrade, offering powder-coated calipers that provide excellent corrosion resistance. Raybestos is a well-respected brand that offers new calipers with a zinc coating for durability, making them a reliable choice.
- Standard/Mid-Grade (Cardone, Centric, Dynamic Friction): These brands offer a wide range of options. Cardone is a huge name in the industry, and their coated 'Ultra' line is a popular choice, though experiences with remanufactured parts can be mixed. Centric is another major supplier of quality aftermarket brake components.
- Economy (BBB Industries, Crown Automotive): These brands provide a cost-effective solution. Crown is known for Jeep replacement parts but also supports other Chrysler vehicles. While functional, they may not have the advanced coatings or longevity of premium brands.
Pro Tip: It is highly recommended to replace brake calipers in pairs (both front or both rear) to ensure even braking performance. Also, always replace the brake pads and flush the brake fluid when installing a new caliper.

Frequently Asked Questions
Do I need to buy a caliper with the mounting bracket?
Most of the time, you can reuse your existing mounting bracket. However, if the bracket is heavily rusted or the slide pins are seized, it's better to buy a new caliper that includes the bracket for a trouble-free installation.
Can I rebuild my Aspen's original caliper?
Rebuilding a caliper with new seals and pistons is possible for experienced DIY mechanics. However, given the affordable cost of new aftermarket calipers and the critical safety function of the part, replacement is often the safer and more reliable option.
🎬 Watch: How to rebuild your Aspen's original front calipers.What is a 'core charge'?
A core charge is a deposit you pay when buying a remanufactured part. You get the deposit back when you return your old caliper. This doesn't apply if you are buying a brand new aftermarket caliper.
Why do I need to bleed the brakes after replacing a caliper?
When you disconnect the brake hose, air enters the hydraulic system. Air is compressible and will result in a spongy pedal with no stopping power. Bleeding the brakes removes all the air, ensuring the system is filled only with incompressible brake fluid for firm, responsive braking.
